From d08605a64e67944eaecfb0e6340f633e01376951 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Tue, 3 Jul 2018 00:28:28 +0200 Subject: ARM: OMAP1: ams-delta: move late devices back to init_machine Initialization of several Amstrad Delta devices was once moved to late_initcall by commit f7519d8c8290 ("ARM: OMAP1: ams-delta: register latch dependent devices later"). The purpose of that move was to allow smooth conversion of Amstrad Delta latches to GPIO. After successful conversion only ams_delta_serio driver was moved back to device_initcall by commit 8d09a1bb3147 ("input: serio: ams-delta: toggle keyboard power over GPIO"). Registration of ams-delta-nand and lcd_ams_delta devices was kept in late_initcall in order to avoid corrupt data reported by the serio driver on boot. Registration of cx20442-codec device was kept there for it to be probed after a regulator on which it depended was ready. The issue of "keybrd_dataout" GPIO pin not initilized to GPIO_OUT_LOW before other latch2 pins causing the corruption have been apparently fixed by commit 5322c19b117a ("ARM: OMAP1: ams-delta: Hog "keybrd_dataout" GPIO pin"). In turn, the issue of missing regulator has been fixed by commit 50c678772a0b ("ASoC: cx20442: Don't ignore regulator_get() errors."). Simplify the board init code by moving registration of those devices back to init_machine.
