linux-toradex.git/drivers/clk/versatile/clk-integrator.c, branch v3.9.7 Linux kernel for Apalis and Colibri modules clk: make ICST driver handle the VCO registers 2012-11-21T19:02:20+00:00 Linus Walleij linus.walleij@linaro.org 2012-11-20T22:01:04+00:00 7a9ad671ac0a0ec2fc86887a9416f837c0cfb801 It turns out that all platforms using the ICST VCO are really just touching two registers, and in the same way as well: one register with the VCO configuration as such, and one lock register that makes it possible to write to the VCO. Factor this register read/write into the ICST driver so we can reuse it in the IM-PD1 driver.

clk: add GPLv2 headers to the Versatile clock files 2012-11-21T19:02:00+00:00 Linus Walleij linus.walleij@linaro.org 2012-11-20T21:39:31+00:00 401301ccdf516fa4b3b90216414a2a15fb826208 The GPLv2 headers were missing and the subsystem maintainer likes them so put them in.

ARM: integrator: convert to common clock 2012-07-12T00:58:45+00:00 Linus Walleij linus.walleij@linaro.org 2012-06-11T15:33:12+00:00 a613163dff04cbfcb7d66b06ef4a5f65498ee59b This converts the Integrator platform to use common clock and the ICST driver. Since from this point not all ARM reference platforms use the clock, we define CONFIG_PLAT_VERSATILE_CLOCK and select it for all platforms except the Integrator. Open issue: I could not use the .init_early() field of the machine descriptor to initialize the clocks, but had to move them to .init_irq(), so presumably .init_early() is so early that common clock is not up, and .init_machine() is too late since it's needed for the clockevent/clocksource initialization. Any suggestions on how to solve this is very welcome.
