omap: am33xx: enable gpio support This patch uses the code in omap-common to support gpio modules 1-3 on am33xx based boards. It adds base address and register definitions, enables clocks to the modules, and enables building the common gpio code for CONFIG_AM33XX as well as CONFIG_OMAP Signed-off-by: Steve Sakoman <steve@sakoman.com>

ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5 The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs. These SoCs have different gpio count but currently omap_gpio driver uses hard coded 192 which is wrong. This patch fixes this issue by: 1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h. 2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5. Thanks for Lubomir Popov to provide valuable comments to fix this issue.

ARM: AM43xx: GP-EVM: Correct GPIO used for VTT regulator control Schematic indicates GPIO5_7 is to be used for VTT regulator control rather than GPIO0_21 so modify enable_vtt_regulator to reflect this.

Below is the brief description of DDR3 init sequence(SW leveling): -> Enable VTT regulator -> Configure VTP -> Configure DDR IO settings -> Disable initialization and refreshes until EMIF registers are programmed. -> Program Timing registers -> Program leveling registers -> Program PHY control and Temp alert and ZQ config registers. -> Enable initialization and refreshes and configure SDRAM CONFIG register Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
