2008-11-20MIPS: RB532: Provide functions for gpio configurationPhil Sutter1-120/+73
As gpiolib doesn't support pin multiplexing, it provides no way to access the GPIOFUNC register. Also there is no support for setting interrupt status and level. These functions provide access to them and are needed by the CompactFlash driver. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-11-20MIPS: RB532: GPIO register offsets are relative to GPIOBASEFlorian Fainelli1-1/+1
This patch fixes the wrong use of GPIO register offsets in devices.c. To avoid further problems, use gpio_get_value to return the NAND status instead of our own expanded code. Also define the zero offset of the alternate function register to allow consistent access.

2008-10-27MIPS: RB532: Set gpio interrupt status and level for CompactFlashFlorian Fainelli1-0/+4
This patch sets the correct interrupt status and level in order to get the CompactFlash adapter working. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2008-10-11MIPS: RB532: Convert to GPIO libFlorian Fainelli1-67/+161
This patch converts the rb532 code to use gpio library and register its gpio chip. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-11MIPS: RB532: Cleanup the headers againFlorian Fainelli3-6/+6
This patch cleans up headers and regroups informations to where they should reside. While moving, try to have a consistant naming for defines. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-11MIPS: RB532: Remove obsolute reference to setup_serial_portFlorian Fainelli1-2/+0
We are no longer using setup_serial_port. So just remove it from the prom code. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-11MIPS: RB532: Fix id usage in platform devicesFlorian Fainelli1-3/+3
When there is only platform device of the same type, id = -1 should be used, fix this. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-11MIPS: RB532: replace raw volatile read with a readlFlorian Fainelli1-1/+1
This patch replaces a raw read using volatiles with a readl. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-11MIPS: RB532: Remove gpio bootup stateFlorian Fainelli1-10/+0
We are no longer using gpio bootup state, so do not export it and do not parse the kernel command line tag for it. Instead we provide gpio-keys for the button the gpio bootup state was checking. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-11MIPS: RB532: Use physical addresses for gpio and device controller registersFlorian Fainelli1-4/+4
This patch fixes the misuse of virtual addresses for the GPIO and third device controller which would lead to problems while accessing ioremap'd registers. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-11MIPS: RB532: Cleanup and group definitions to their right placesFlorian Fainelli1-14/+2
This patch moves GPIO related definitions to gpio.h and IRQ related to irq.h Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-08-26[MIPS] RB532: Do not define registers that are already definedFlorian Fainelli1-13/+3
Use the register definitions of the MPMC controller from mach-rc32434/rb.h instead of redefining them. Signed-off-by: Florian Fainelli <florian.fainelli@telecomint.eu> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
