Subject: imx93_evk: Drop UART pad settings
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4e35201505d27a47e16fb63c78eff97b6c646441;p=thirdparty%2Fu-boot.git

imx93_evk: Drop UART pad settings

With DM_SERIAL and pinctrl driver, the UART pad settings in board code
could be dropped. Then drop board_early_init_f(), since it is a dummy
function now.

While at here, remove WDOG_PAD_CTRL, since no user.
