From 18403424c4fe5bac509bf52343f5d5407d45ee3a Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Mon, 6 Feb 2012 11:22:21 -0800 Subject: ARM: ux500: pass parent pointer to each platform device This patch provides a means for any device within ux500 platform code to allocate its own parent. This is particularly prudent with the introduction of /sys/devices/socX, as a device can now proclaim to be integral part of an SoC, rather than a more generic platform device. Latter patches make good use of this functionality.

UART1/A is typically used on Cardhu, and is the option we assume here. For now, only enable UART1/A, and explicitly disable all other ports. The explicit disable prevents the message "of_serial 70006040.serial: no clock-frequency property set" being printed during boot. Enabling the other ports requires their clocks to be enabled, or accesses to the registers will hang. At present, this requires adding entries into board-dt-tegra30.c's tegra_dt_clk_init_table[]. Lets punt on that and wait for the common clock bindings to set this all up, although that will also requiring adding clock support to 8250.c. While we're at it, fix board-dt-tegra30.c to enable the correct clock for the debug UART. We got away with this before, because the bootloader already enabled it.

ARM: EXYNOS: support EINT for EXYNOS4 and EXYNOS5 The GPIOs of EXYNOS4 and EXYNOS5 are changed to use ioremap instead of static mapping. It alse causes the change of external interrupt IO mapping. This patch changes EXYNOS4 to EXYNOS for common use and changes EINT_x macros for supporting dynamic IO mapping.
