* aw_mmc: Reset cardTom Jones2026-02-092-0/+12
| | | | | | | | | | | | | | | On H616 (and I think H6, but this isn't verified) we need to reset the card to have a functioning device. With this commit all my pending patches for H616 are in tree. We run well on my test device (Orange Pi Zero3), however there is an uninvestigated issue with ethernet and graphics are an open question.

* aw_rtc: bump settime() delaysMitchell Horne2025-12-151-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | There are delay loops, checking the BUSY status bit, before writing to the date or time registers. Each iteration contains a 1usec delay, for a maximum of 70 iterations. This is frequently not enough on the D1 platform, where the message is emitted: rtc0: could not set date, RTC busy Bump the loop delay to 10usecs each, and the maximum number of iterations to 150, for a maximum delay of 1.5msecs between each write of the register. In my testing this seems to be adequate. The loop variable is renamed for clarity/simplicity.

| | | | | | | | | | | | | | | | | | | | | (Second attempt.) For the Allwinner D1 (Nehza) SBC. This RTC driver is also a clock provider, which registers two fixed clocks. In all the devices we currently support, the names of the clocks are present in the "clock-output-names" property of the device tree. This is not the case for the D1 DTS, as this property does not appear in upstream. Therefore the clock definitions are statically assigned a name, which is overridden when specified. The driver also supports the older A10/A20 models, which don't export any clocks. Ensure this case is handled properly.

* sound: Make device registration more intuitiveChristos Margiolis2024-11-031-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | The way a sound driver currently registers to sound(4) is using the following sequence of function calls: 1. pcm_register() to initialize snddev_info. 2. pcm_addchan() calls to create the device's primary channels. 3. pcm_setstatus() to do the final setup. While using 3 different functions in a specific order might not be very elegant, this pattern cannot be easily avoided. However, pcm_register() and pcm_setstatus() are especially confusing, since one would intuitively expect: 1. pcm_register() to actually do the registration, as opposed to a basic initialization. 2. pcm_setstatus() to, as the name suggests, set some kind of status, as opposed to finalizing the registration. This patch renames pcm_register() to pcm_init(), and pcm_setstatus() to pcm_register(). Drivers are modified accordingly.
