2016-04-15clk: at91: fix check of clk_register() returned valueVladimir Zapolskiy
The clk_register() function returns a valid pointer to struct clk or ERR_PTR() error code, this makes a check for returned NULL value useless and may lead to oops on error path.

2016-02-17clk: at91: remove useless includesAlexandre Belloni
Over time, some includes were copy pasted from other clocks drivers but are not necessary. Acked-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
2016-02-17clk: at91: make use of syscon/regmap internallyBoris Brezillon
Use the regmap coming from syscon to access the registers instead of using pmc_read/pmc_write. This allows to avoid passing the at91_pmc structure to the child nodes of the PMC. The final benefit is to have each clock register itself instead of having to iterate over the children.

2014-09-22clk: at91: add a driver for the h32mx clockAlexandre Belloni
Newer SoCs have two different AHB interconnect. The AHB 32 bits Matrix interconnect (h32mx) has a clock that can be setup at the half of the h64mx clock (which is mck). The h32mx clock can not exceed 90 MHz.
