From f7519d8c8290765a9408a52db4ba4a368ff72ca5 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Tue, 20 Dec 2011 22:54:18 +0100 Subject: ARM: OMAP1: ams-delta: register latch dependent devices later In preparation to converting Amstrad Delta on-board latches to basic_mmio_gpio devices, registration of platform devices which depend on latches and will require initialization of their GPIO pins first, should be moved out of .machine_init down to late_initcall level, as the gpio-generic driver is not available until device_initcall time. The latch reset operation, which will be replaced with GPIO initialization, must also be moved to late_initcall for the same reason. Since there was already another, separate arch_initcall function for setting up one of those latch dependent devices, the on-board modem device, reuse that function, i.e., rename it to a name that matches the new purpose, extend with other device setup relocated from .machine_init, and move down to the late_initcall level. While being at it, add missing gpio_free() in case the modem platform device registration fails. Thanks to Tony Lindgren who suggested this approach instead of shifting up the gpio-generic driver initialization. In addition, defer registration of the Amstrad Delta ASoC and serio devices, done from their device driver files, until late_initcall time, as those drivers will depend on their GPIO pins already requested from the board late_init() function until updated to register their GPIO pins themselves.

Even more, some custom ams-delta only drivers can perhaps be dropped from the tree after converting selected ams-delta platform devices to follow generic GPIO based device models. The latch_gpios[] table is initially filled with all latch1 and latch2 GPIO pins in order to register and initialize them from the board file until those are handled by respective existing device drivers (leds, nand, lcd, serio, asoc, serial). That table will get almost empty after the transision process is completed, holding only pins not used by any drivers / connected to unused devices, in order to initialize them from the board file for power saving purposes. The new ams_delta_latch_write() function is a unified replacement for those removed ams_delta_latch[12]_write(), and serves as a temporary wrapper over gpio_set_value(), providing the old API for those not yet updated device drivers, and will be removed after all custom drivers are converted or replaced.

While requesting and initializing GPIO pins used, also take care of one extra pin KEYBRD_DATAOUT which, even if not used by the driver, belongs to the device and affects its functioning. Once done, move the driver initialization back to the device_initcall level, reverting the temporary chane introduced with patch 1/7 "ARM: OMAP1: ams-delta: register latch dependent devices later". That change is no longer required once the driver takes care of registering used GPIO pins, and it's better to initialize the device before others using the latch2 based GPIO pins, otherwise a garbage is reported on boot, perhaps due to random data already captured by the FIQ handler while the keyboard related latch bits are written with random values during initialization of those other latch2 dependent devices.
