[ Upstream commit 84822215 ] The WCD938x comes with three devices on two Linux drivers: 1. RX Soundwire device (wcd938x-sdw.c driver), 2. TX Soundwire device, which is used to access devices via regmap (also wcd938x-sdw.c driver), 3. platform device (wcd938x.c driver) - glue and component master, actually having most of the code using TX Soundwire device regmap. When RX and TX Soundwire devices probe, the component master (platform device) bind tries to write micbias configuration via TX Soundwire regmap. This might happen before TX Soundwire enumerates, so the regmap access fails. On Qualcomm SM8550 board with WCD9385: qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops) wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops) qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow Fix the issue by: 1. Moving the regmap creation from platform device to TX Soundwire device. The regmap settings are moved as-is with one difference: making the wcd938x_regmap_config const. 2. Using regmap in cache only mode till the actual TX Soundwire device enumerates and then sync the regmap cache.

[ Upstream commit 14705f96 ] On my RTW8821CU chipset rfe_option reads as 0x22. Looking at the vendor driver suggests that the field width of rfe_option is 5 bit, so rfe_option should be masked with 0x1f. Without this the rfe_option comparisons with 2 further down the driver evaluate as false when they should really evaluate as true. The effect is that 2G channels do not work. rfe_option is also used as an array index into rtw8821c_rfe_defs[]. rtw8821c_rfe_defs[34] (0x22) was added as part of adding USB support, likely because rfe_option reads as 0x22. As this now becomes 0x2, rtw8821c_rfe_defs[34] is no longer used and can be removed. Note that this might not be the whole truth. In the vendor driver there are indeed places where the unmasked rfe_option value is used. However, the driver has several places where rfe_option is tested with the pattern if (rfe_option == 2 || rfe_option == 0x22) or if (rfe_option == 4 || rfe_option == 0x24), so that rfe_option BIT(5) has no influence on the code path taken. We therefore mask BIT(5) out from rfe_option entirely until this assumption is proved wrong by some chip variant we do not know yet.

commit 3eeca5e5 upstream. The adreno_load_gpu() path is guarded by an error check on adreno_load_fw(). This function is responsible for loading Qualcomm-only-signed binaries (e.g. SQE and GMU FW for A6XX), but it does not take the vendor-signed ZAP blob into account. By embedding the SQE (and GMU, if necessary) firmware into the initrd/kernel, we can trigger and unfortunate path that would not bail out early and proceed with gpu->hw_init(). That will fail, as the ZAP loader path will not find the firmware and return back to adreno_load_gpu(). This error path involves pm_runtime_put_sync() which then calls idle() instead of suspend(). This is suboptimal, as it means that we're not going through the clean shutdown sequence. With at least A619_holi, this makes the GPU not wake up until it goes through at least one more start-fail-stop cycle. The pm_runtime_put_sync that appears in the error path actually does not guarantee that because of the earlier enabling of runtime autosuspend. Fix that by using pm_runtime_put_sync_suspend to force a clean shutdown. Test cases: 1. All firmware baked into kernel 2. error loading ZAP fw in initrd -> load from rootfs at DE start Both succeed on A619_holi (SM6375) and A630 (SDM845).

commit 17d793f3 upstream. To fully utilize the BT polling/refresh rate, a few input events are sent together to reduce event delay. This causes issue to the timestamp generated by input_sync since all the events in the same packet would pretty much have the same timestamp. This patch inserts time interval to the events by averaging the total time used for sending the packet. This decision was mainly based on observing the actual time interval between each BT polling. The interval doesn't seem to be constant, due to the network and system environment. So, using solutions other than averaging doesn't end up with valid timestamps.

commit 11e0b006 upstream. The `amdgpu_ucode_request` helper will ensure that the return code for missing firmware is -ENODEV so that early_init can fail. The `amdgpu_ucode_release` helper provides symmetry for releasing firmware.

commit 2210af50 upstream. All microcode runs a basic validation after it's been loaded. Each IP block as part of init will run both. Introduce a wrapper for request_firmware and amdgpu_ucode_validate. This wrapper will also remap any error codes from request_firmware to -ENODEV. This is so that early_init will fail if firmware couldn't be loaded instead of the IP block being disabled.
