`@patch/kernel/archive/meson64-6.18/general-meson-mmc-2-arm64-amlogic-dts-meson-update-meson-axg-device-tree.patch`:
- Line 30: Align the MMC property schema by defining amlogic,mmc-phase as a
three-cell array and using that singular name consistently in both target
binding patches, including their examples. Apply the DTS-side correction at
patch/kernel/archive/meson64-6.18/general-meson-mmc-2-arm64-amlogic-dts-meson-update-meson-axg-device-tree.patch
lines 30 and 38, and
patch/kernel/archive/meson64-7.2/general-meson-mmc-2-arm64-amlogic-dts-meson-update-meson-axg-device-tree.patch
lines 30 and 38; ensure sd_emmc_b and sd_emmc_c use the schema-approved
property.
In `@patch/kernel/archive/rockchip64-6.18/temporary-workaround-dma-reset.patch`:
- Line 20: Update stmmac_init_dma_engine so the reset workaround clears
stmmac_reset() errors only for the known Rockchip reset condition; preserve and
return all other failures. Before reporting successful DMA initialization, add
the required hardware readiness check and fail if the engine is not ready.

Outside diff comments:
In
`@patch/kernel/archive/meson64-6.18/board-odroidc2-usb-hub-disable-autosuspend-for-Genesys-Logic-.patch`:
- Around line 22-27: Scope the HUB_QUIRK_DISABLE_AUTOSUSPEND change in
hub_id_table to ODROID-C2/GXBB only, using an explicit platform check or
restricting the patch to that kernel build; retain
HUB_QUIRK_CHECK_PORT_AUTOSUSPEND for other platforms and apply the same
correction to the 7.2 payload.
In `@patch/kernel/archive/rockchip64-6.18/general-cryptov1-trng.patch`:
- Around line 190-198: Update rk_cipher_run so rkc->lock remains balanced and
held across rk_cipher_hw_init and the DMA/completion sequence, adding the
matching lock acquisition before shared hardware access and retaining only the
corresponding unlock after completion; preserve serialization with TRNG and hash
users.
- Line 221: Update rk3288_trng_read to handle wait == false before acquiring the
lock, starting runtime PM, or polling; return immediately when no data is
already available, while preserving the existing blocking behavior for wait ==
true.
- Around line 253-258: Update the timeout cleanup in the TRNG read flow around
readl_poll_timeout and the readfail label to clear RK_CRYPTO_TRNG_START before
releasing the lock and runtime-PM reference. Preserve the existing cleanup and
success-path behavior.
- Around line 85-86: Update the HWRNG registration flow around
rk3288_hwrng_register to handle registration failure before cleanup: propagate
the failure and unwind rk_crypto_unregister(), or track successful registration
so hwrng_unregister() is only called for registered objects. Preserve normal
probe behavior on successful registration.
- Line 170: In rk_crypto_probe(), initialize crypto_info->lock with mutex_init()
before registering crypto algorithms or HWRNG support. Ensure all reachable hash
and TRNG paths using this mutex operate only after initialization.
- Around line 166-179: Split rk_hash_run cleanup into pre-lock and post-lock
paths: route rk_hash_prepare() failures and unsupported-digest exits to cleanup
that skips mutex_unlock(&rkc->lock), while keeping errors after
mutex_lock(&rkc->lock) on the unlock cleanup path. Preserve PM runtime cleanup
for all exits and the direct return on pm_runtime_resume_and_get() failure.
In
`@patch/kernel/archive/rockchip64-6.18/general-dw-wdt-4-hold-reset-across-suspend.patch`:
- Line 42: Update the error branch near the clock preparation logic to jump to
the existing unprepare_clk label instead of unprepare_pclk, ensuring this patch
compiles independently and both clocks are disabled during cleanup.
In `@patch/kernel/archive/rockchip64-6.18/rk3308-0001-pinctrl-slew-mux.patch`:
- Around line 211-212: Remove the schmitt_calc_reg null check and its -ENOTSUPP
return from the rockchip_get_mux path, since mux readback does not depend on
Schmitt support. Preserve the existing IOMUX register read behavior so RK2928
mux banks continue to work without schmitt_calc_reg.
In `@patch/kernel/archive/rockchip64-7.2/general-cryptov1-trng.patch`:
- Around line 190-198: In rk_cipher_run, replace the mutex_unlock before
rk_cipher_hw_init with mutex_lock so the lock is acquired before hardware setup
and remains held through DMA start and completion waiting; retain the later
mutex_unlock as the single release.
- Line 178: Update the cleanup flow around rk_hash_prepare(), digest validation,
and theend so mutex_unlock(&rkc->lock) runs only after a successful
mutex_lock(&rkc->lock). Route pre-lock failures through cleanup that omits the
unlock or track lock ownership explicitly, while preserving the PM-resume
failure as a direct return.
- Line 170: Initialize rkc->lock with mutex_init during crypto-device setup,
before any hash, cipher, or TRNG request can access it; keep the existing
mutex_lock usage unchanged.
- Around line 85-86: Update rk_crypto_probe() so it captures and checks the
return value from rk3288_hwrng_register() when crypto_info->variant->trng is
enabled; on failure, return through the existing err_register_alg cleanup path,
ensuring rk_crypto_remove() is reached only after successful HWRNG registration.
- Around line 253-258: Update rk3288_trng_read so the RK_CRYPTO_TRNG_START clear
write occurs in the readfail cleanup path before unlocking and releasing runtime
PM, ensuring it also runs when readl_poll_timeout fails. Remove the existing
success-only clear write and preserve the normal unlock and cleanup flow.
- Around line 221-257: Update rk3288_trng_read to honor nonblocking requests by
returning 0 immediately when wait is false, before runtime-PM, mutex
acquisition, or TRNG operations; preserve the existing blocking path when wait
is true.
In
`@patch/kernel/archive/rockchip64-7.2/general-drv-net-phy-Add-maxio-phys-driver.patch`:
- Around line 133-148: Update both paged PHY helper functions around the
MAXIO_PAGE_SELECT read to immediately return the negative oldpage error when the
initial PHY_READ fails, before attempting the restore write. Preserve the
existing page-switch, operation, and restoration flow for successful reads, and
ensure the failure is propagated instead of returning success.
In `@patch/kernel/archive/rockchip64-7.2/rk3308-0001-pinctrl-slew-mux.patch`:
- Around line 211-212: Remove the schmitt_calc_reg availability check from the
PIN_CONFIG_MUX getter so RK2928 can reach rockchip_get_mux() and read the mux
value without Schmitt support.
In
`@patch/kernel/archive/rockchip64-7.2/rk3562-0005-net-stmmac-dwmac-rk-add-RK3562-GMAC-support.patch`:
- Around line 164-165: Update rk3562_set_gmac_speed so GMAC0 RGMII speed changes
program RK3562_GRF_SYS_SOC_CON0 with the required divider values: DIV50 for 10
Mbps, DIV5 for 100 Mbps, and DIV1 for 1000 Mbps. Do not let the !bsp_priv->id
early return bypass GMAC0 RGMII handling, while preserving the existing RMII
speed behavior for GMAC1.
In
`@patch/kernel/archive/rockchip64-7.2/rk3562-0010-drm-rockchip-add-RK3562-VOP2-support.patch`:
- Around line 72-73: In vop2_bind(), preserve errors returned by
rockchip_csu_get() instead of converting vop2->csu_aclk to NULL; return the
error through dev_err_probe(). Update rockchip_csu_get() so an unavailable or
not-yet-probed CSU provider returns -EPROBE_DEFER, while unmatched clock lookups
retain -ENOENT.
In `@patch/kernel/archive/rockchip64-7.2/temporary-workaround-dma-reset.patch`:
- Around line 26-27: Remove the unconditional ret = 0 handling after
stmmac_reset() in the DMA initialization path. Preserve reset failures for
general stmmac hardware, and apply the reduced-throughput workaround only when
an explicit Rockchip SoC quirk is detected, using the existing platform/quirk
identification symbols.
