ARM: at91: remove old at91-specific clock driver

2014-11-26T17:43:44+00:00

This clock driver collection was specific to AT91 and only used in !DT cases. All clocks and the clock trees for all Atmel SoCs are now described by drivers using the common clock framework. Signed-off-by: Nicolas Ferre Acked-by: Boris BREZILLON

ARM: at91/PMC: don't forget to write PMC_PCDR register to disable clocks

2014-09-24T16:00:42+00:00

When introducing support for sama5d3, the write to PMC_PCDR register has been accidentally removed. Reported-by: Nathalie Cyrille Signed-off-by: Ludovic Desroches Signed-off-by: Nicolas Ferre Cc: # 3.10.x and later

ARM: at91: remove AT91_PROGRAMMABLE_CLOCKS configuration option

2013-12-12T17:57:42+00:00

This AT91 specific Kconfig option removed the code that dealt with programmable clocks. Each AT91 SoC embeds programmable clocks and there is little gain to remove this code in case that such a clock is not used. If this option is not selected, it causes certain drivers to fail to build. We simply remove this option instead of adding code just to build a workaround.

ARM: at91: add new compatible strings for pmc driver

2013-12-02T14:31:27+00:00

This patch adds new compatible string for PMC node to prepare the transition to common clk. These compatible string come from pmc driver in clk subsystem and are needed to provide new device tree compatibility with old at91 clks (device tree using common clks will use the new compatible strings).

ARM: at91: move at91_pmc.h to include/linux/clk/at91_pmc.h

2013-12-02T14:22:15+00:00

This patch moves at91_pmc.h header from machine specific directory (arch/arm/mach-at91/include/mach/at91_pmc.h) to clk include directory (include/linux/clk/at91_pmc.h). We need this to avoid reference to machine specific headers in clk drivers. Signed-off-by: Boris BREZILLON Acked-by: Felipe Balbi Acked-by: Mike Turquette Signed-off-by: Nicolas Ferre

ARM: at91/PMC: use at91_usb_rate() for UTMI PLL

2013-06-26T13:24:11+00:00

We are using this function, now that we have introduced the support for UTMI clock for computing the USB host rate. Signed-off-by: Nicolas Ferre Tested-by: Bo Shen

ARM: at91/PMC: fix at91sam9n12 USB FS init

2013-06-26T13:23:18+00:00

at91sam9n12 has Full-speed only USB. So we should add it to the list in at91_pllb_usbfs_clock_init() function. Moreover, at91sam9n12 has an unusual PMC in the sense that it has a PLLB but also has a USB clock register. Signed-off-by: Nicolas Ferre Tested-by: Bo Shen

ARM: at91/PMC: at91sam9n12 family has a PLLB

ARM: at91/PMC: sama5d3 family doesn't have a PLLB

ARM: at91: introduce SAMA5 support

2013-03-26T11:18:04+00:00

This patch introduces the SAMA5 support and a generic board file for SAMA5 devices. It also updates the PMC driver to manage clock division which is a requirement since some peripherals can't work at the bus frequency on SAMA5.
