| * | clk: at91: keep slow clk enabled to prevent system hang | Boris Brezillon | 2015-01-13 | 1 | -0/+27 |
| | | | | | | | | | | | | | | | | | All slow clk users are not properly claiming it (get + prepare + enable) before using it. If all users properly claiming this clock release it, the clock is disabled, but faulty users still depends on it, and the system hangs. This fix prevents the slow clock from being disabled, and should solve the hanging issue, but offending drivers should be patched to properly claim this clock.

| * | clk: at91: fix num_parents test in at91sam9260 slow clk implementation | Boris BREZILLON | 2014-09-02 | 1 | -1/+1 |
| | | | | | | | | | The slow clk block provided by at91sam9260 and derived SoCs should always have 2 parents. Signed-off-by: Boris BREZILLON <boris.brezillon@free-electrons.com> Signed-off-by: Mike Turquette <mturquette@linaro.org> | ||||
| * | clk: at91: add slow clks driver | Boris BREZILLON | 2014-05-07 | 1 | -0/+467 |
| AT91 slow clk is a clk multiplexer. In some SoCs (sam9x5, sama5, sam9g45 families) this multiplexer can choose among 2 sources: an internal RC oscillator circuit and an oscillator using an external crystal. In other Socs (sam9260 family) the multiplexer source is hardcoded with the OSCSEL signal.
