* ARM: mxs: remove old clock supportShawn Guo2012-05-091-803/+0
| | | | | | | The mxs clock has been switched to common clock framework, so the old clock support can be removed now. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

They are typically the platform side of a change in the drivers directory, such as adding a new driver or extending the interface to the platform. In cases where there is no maintainer for the driver, or the maintainer prefers to have the platform changes in the same branch as the driver changes, the patches to the drivers are included as well. A much smaller set of driver updates that depend on other branches getting merged first will be sent later. The new export of tegra_chip_uid conflicts with other changes in fuse.c. In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with the cleanup of the interrupt handling of that driver.

* | ARM: i.MX28: shift frac value in _CLK_SET_RATEMatt Burtch2011-10-251-1/+1
|/ | | | | | | | | | | | | | | | | Noticed when setting SSP0 in clk_set_rate, _CLK_SET_RATE attempts to reset the clock divider for the SSP0 parent clock, in this case IO0FRAC. Bits 24-29 of HW_CLKCTRL_FRAC0 are cleared correctly, but when the new frac value is written the value isn't shifted up to write the correct bit-field. This results in IO0FRAC being set to 0 and CPUFRAC being corrupted. This should occur when writing IO1FRAC, EMIFRAC in HW_CLKCTRL_FRAC0 and GPMIFRAC, HSADCFRAC in HW_CLKCTRL_FRAC1. Tested on custom i.MX28 board with SSP0 SPI driver. Signed-off-by: Matt Burtch <matt@grid-net.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: mxs/clock-mx28: fix up name##_set_rateUwe Kleine-König2011-04-121-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the lcdif clock get_rate looks as follows: read div from HW_CLKCTRL_DIS_LCDIF.DIV return clk_get_rate(clk->parent) / div with clk->parent being ref_pix_clk on my system. ref_pix_clk's rate depends on HW_CLKCTRL_FRAC1.PIXFRAC. The set_rate function for lcdif does: parent_rate = clk_get_rate(clk->parent); based on that calculate frac and div such that parent_rate * 18 / frac / div is near the requested rate. HW_CLKCTRL_FRAC1.PIXFRAC is updated with frac HW_CLKCTRL_DIS_LCDIF.DIV is updated with div For this calculation to be correct parent_rate needs to be initialized not with the clock rate of lcdif's parent (i.e. ref_pix) but that of its grandparent (i.e. ref_pix' parent == pll0_clk). The obvious downside of this patch is that now set_rate(lcdif) changes its parent's rate, too. Still this is better than a wrong rate.
