* [media] clock-sh7724.c: fix sh-vou clock identifierHans Verkuil2015-07-061-1/+1
| | | | | | | | | | | Bitrot has set in for this driver and the sh-vou clock was never enabled, since the clock name in clock-sh7724.c was wrong. It should be sh-vou, not sh-vou.0.

* serial: sh-sci: clkdev updates for MSTP gating.Paul Mundt2010-03-101-6/+6
| | | | | | | | | | | | | | | | This fixes up some of the I/D/F clock ambiguity in the sh-sci driver. The interface clock in most cases just wraps back to the peripheral clock, while the function clock wraps in to the MSTP bits. As the logic was somewhat inverted, this cleans that up, and also enables all CPUs with SCI MSTP bits to match function clocks through clkdev lookup. As a result, this gets rid of the clk string abuse on the sh side, and the clock string will be killed off once the ARM code has had a chance to sync up. This also enables MSTP gating on CPUs like 7786 which had never wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785, and SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: always enable sh7724 vpu_clk and set to 166MHz on EcovecMagnus Damm2010-02-221-1/+1
| | | | | | | | | | | | | Update the sh7724 processor code to always enable vpu_clk. On the Ecovec board, set the vpu_clk to 166 Mhz. The 166MHz setting results in a divide-by-6 setup for vpu_clk and improves the VPU performance compared to the power-on-reset/bootloader configuration.

A sh7724 specific kick function is also added that updates the KICK bit whenever div4 clocks in FRQCRA and FRQCRB have been set. Allows us to set the VPU clock.
