ARM: pxa2xx: Fix GPIO descriptor tables

2022-07-22T13:03:08Z

Laurence reports: "Kernel >5.18 on Zaurus has a bug where the power management code can't talk to devices, emitting the following errors: sharpsl-pm sharpsl-pm: Error: AC check failed: voltage -22. sharpsl-pm sharpsl-pm: Charging Error! sharpsl-pm sharpsl-pm: Warning: Cannot read main battery! Looking at the recent changes, I found that commit 31455bbda208 ("spi: pxa2xx_spi: Convert to use GPIO descriptors") replaced the deprecated SPI chip select platform device code with a gpiod lookup table. However, this didn't seem to work until I changed the `dev_id` member from the device name to the bus id. I'm not entirely sure why this is necessary, but I suspect it is related to the fact that in sysfs SPI devices are attached under /sys/devices/.../dev_name/spi_master/spiB/spiB.C, rather than directly to the device." After reviewing the change I conclude that the same fix is needed for all affected boards.

ARM: pxa: move mach/*.h to mach-pxa/

2022-05-07T20:56:17Z

None of the headers are included from outside of the mach-pxa directory, so move them all in there. Signed-off-by: Arnd Bergmann

ARM: pxa: spitz: use gpio descriptors for audio

2022-05-07T20:55:47Z

The audio driver should not use a hardwired gpio number from the header. Change it to use a lookup table. Acked-by: Mark Brown Cc: alsa-devel@alsa-project.org Reviewed-by: Linus Walleij Signed-off-by: Arnd Bergmann

spi: pxa2xx_spi: Convert to use GPIO descriptors

2022-01-31T15:17:27Z

This converts the PXA2xx SPI driver to use GPIO descriptors exclusively to retrieve GPIO chip select lines. The device tree and ACPI paths of the driver already use descriptors, hence ->use_gpio_descriptors is already set and this codepath is well tested. Convert all the PXA boards providing chip select GPIOs as platform data and drop the old GPIO chipselect handling in favor of the core managing it exclusively.

backlight: corgi: Convert to use GPIO descriptors

2020-03-25T09:30:46Z

The code in the Corgi backlight driver can be considerably simplified by moving to GPIO descriptors and lookup tables from the board files instead of passing GPIO numbers using the old API. Make sure to encode inversion semantics for the Akita and Spitz platforms inside the GPIO lookup table and drop the custom inversion semantics from the driver. All in-tree users are converted in this patch. Signed-off-by: Linus Walleij Acked-by: Robert Jarzmik Reviewed-by: Daniel Thompson Signed-off-by: Lee Jones

It's also a slave controller driver now, calling it "master" is slightly misleading. Signed-off-by: Lubomir Rintel Acked-by: Robert Jarzmik Signed-off-by: Mark Brown

mmc: pxa: Use GPIO descriptor for power

2018-12-17T07:26:24Z

After converting the PXA driver to use GPIO descriptors for card detect and write protect it is relatively simple to convert it to also use a descriptor for getting the optional power control GPIO. The polarity inversion flag can also go away from the platform data since this is indicated in the GPIO machine descriptor table.

ARM: pxa: Delete platform data for CD/WP

2018-12-17T07:26:24Z

This deletes the platform data passed for card detect and write protect from various PXA machines. Make sure to keep .gpio_card_ro_invert as this is still in use by some machines and needed to set the right flag to the MMC core (will be cleaned up later).

ARM: pxa: Add gpio descriptor lookup tables for MMC CD/WP

2018-12-17T07:26:24Z

This adds GPIO descriptor look-up tables for a whole bunch of PXA boards with MMC card detect (CD) and write protect (WP) GPIO lines, so we can move away from the hard-coded GPIO numberspace. In some cases the platforms were compulsively including the header even if they weren't actually using it, and in these cases I simply replaced that inclusion with the more appropriate which is what board files should be including most of the time.
