[PATCH 5.18 04/88] ARM: pxa2xx: Fix GPIO descriptor tables

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Linus Walleij <linus.walleij@linaro.org>

commit c5cdb9286913aa5a5ebb81bcca0c17df3b0e2c79 upstream.

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.
