arm64: a37xx: pinctrl: Improve description for pinmux command

2022-08-09T06:58:27+00:00

In more cases group name consist of function name followed by function
number. So if function name is just prefix of group name, show group name.

So in 'pinmux status -a' command output would be visible also extended
function number, which is useful for debugging.

arm64: a37xx: pinctrl: Fix definitions for MPP pins 20-22

2022-08-09T06:58:27+00:00

All 3 MPP pins (20, 21 and 22) can be configured individually and also can
be configured to GPIO functions. Fix definitions for these MPP pins in
existing pin groups. After this change GPIO function can be enabled just
for one of these 3 pins.

mvebu: pinctrl: apply SDHCI PHY config for A7K

2022-07-29T08:02:43+00:00

Current pin control driver applies SDHCI PHY MUX selection
when board DT calls for eMMC function on MPP wires.
However, for CP side eMMC, only the "armada-8k-cpm-pinctrl"
compatibility string is taken into account, which causes
CP-SDHCI on Armada-7K boards to fail.
This patch adds "armada-7k-pinctrl" compatibility string
handling for the CP-SDHCI PHY configuration case.

arm64: a37xx: pinctrl: Implement gpio_request_enable for gpio functionality

2022-07-29T08:02:43+00:00

To automatically enable GPIO functionality of some MPP pin, it is required
to implement .gpio_request_enable and .gpio_disable_free callbacks in
pinctrl driver and set .request and .rfree callbacks in GPIO driver to
pinctrl_gpio_request / pinctrl_gpio_free functions.
