2010-08-17i.MX35: remove get_3_3_div helper functionSascha Hauer
In the v2 reference manual there are no dividers combined of two dividers. Instead, all dividers are simple 6bit dividers. I assume the combined dividers only exist in preliminary hardware. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2010-08-17mx35: Fix boot ROM hang in internal boot modeHans J. Koch
If a watchdog reset occurs after booting in internal boot mode, the i.MX35 won't boot anymore. The boot ROM code seems to assume that some clocks are turned on (they are after a power-on reset). This patch turns on the necessary clocks. Signed-off-by: Hans J.

2010-02-12ARM: Consolidate clks_register() and similarRussell King
Most machine classes want some way to register a block of clk_lookup structures, and most do it by implementing a clks_register() type function which walks an array, or by open-coding a loop. Consolidate all this into clkdev_add_table().

It is no longer present in newer cores. Unfortunately Freescale decided to put the bit which decides between automotive clock path and consumer clock path in the automotive clock path direction.

2009-03-13[ARM] MX35: add clock supportSascha Hauer
This patch adds clock support for i.MX35 SoCs. We do not support setting of clock rates yet, but most interesting clock rates should be reported. I couldn't test all clock rates and the datasheet contains some obvious bugs, so expect some bugs in this code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
