2014-11-28ARM: vexpress: Remove non-DT codePawel Moll4-142/+0
Now, with the CLCD DT support available, there is no more reason to keep the non-DT support for V2P-CA9. Removed, together with "some" supporting code. It was necessary to make PLAT_VERSATILE_SCHED_CLOCK optional and selected by the machines still interested in it.

2012-11-05ARM: vexpress: Start using new Versatile Express infrastructurePawel Moll1-81/+0
This patch starts using all the configuration infrastructure. - generic GPIO library is forced now - sysreg GPIOs are used as MMC CD and WP information sources; thanks to this MMCI auxiliary data is not longer necessary - DVI muxer and mode control is removed from non-DT V2P-CA9 code as this is now handled by the vexpress-dvi driver - clock generators control is removed as is being handled by the common clock driver now - the sysreg and sysctl control is now delegated to the appropriate drivers and all related code was removed - NOR Flash set_vpp function has been removed as the control bit used does _not_ control its VPP line, but the #WP signal instead (which is de facto unusable in case of Linux MTD drivers); this also allowed the remove its DT auxiliary data The non-DT code defines only minimal required number of the config devices. Device Trees are updated to make use of all new features. Signed-off-by: Pawel Moll <pawel.moll@arm.com>

2012-09-14ARM: make mach/gpio.h headers optionalRob Herring1-1/+0
Most platforms don't need mach/gpio.h and it prevents multi-platform kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX or have lots of implicit includes pulled in by mach/gpio.h. at91 and omap have gpio clean-up pending and can drop CONFIG_NEED_MACH_GPIO_H once that is in.

2012-07-13ARM: vexpress: Config option for early printk consolePawel Moll2-0/+55
Versatile Express platform can be used in different configurations, the console UART used by early printk may be located at different addresses in the address space. This patch makes it possible to select the base address of a PL011 UART to be used as a console output in the kernel configuration. The default behaviour is still the heuristic detecting memory map on Cortex-A core tiles. The zImage decompressor will use the same configuration values or print out nothing if DEBUG_LL is not enabled. Signed-off-by: Pawel Moll <pawel.moll@arm.com>
2012-07-13ARM: vexpress: Initial common clock supportPawel Moll2-15/+19
This patch makes Versatile Express use the common clock framework instead of the plat-versatile implementation. It defines clock provider for VE's OSCs (clock generators) and registers all required fixed and variable clock sources (for both motherboard and core tile). This is a simple conversion of the existing state and will be extended (and migrated to drivers/clk) in the near future. Signed-off-by: Pawel Moll <pawel.moll@arm.com>
2012-07-12ARM: vexpress: Check master site in daughterboard's sysctl operationsPawel Moll1-3/+6
With recent enough motherboard firmware, core tile can be fitted in either of the two daughterboard sites. The non-DT tile code for V2P-CA9 did not check that when configuring DVI output nor setting CLCD pixel clock. Fixed now, providing "get master site" API in motherboard's code.
