Hi Paul & Benoit, Does this series look OK to you guys to queue or ack? * Afzal Mohammed <afzal@xxxxxx> [130802 06:42]: > Hi, > > AM43x PRCM support (excluding clock tree) is being added with this > series. AM43x reuses most of the IP's from AM335x, as that is the > case, much of the AM335x hwmod data is reused. > > I am aware that this series adds around +1K lines to platform. We in > TI, here are making efforts to clean platform code gradually and keep > to minumum the code being added to support new SoC's. Please note that > this SoC support series has positive diffstat of just above 1K only. > This compared to last SoC that was supported in OMAP family during > last merge window is way less (this is only around 1/8th postive > diffstat of it). Clock data is not added in this series, instead > directly clock tree in DT with driver would be used, this is a work in > progress.

But as AM43x PRCM functionality is similar to > OMAP4, power domain, clock domain & hwmod operations are reused from > OMAP4. > > A single header file has been added to provide all AM43x PRCM defines. > > Here sequencewise, initially AM335x hwmod is modified to have it's > fields get updated at runtime (wherever element is shared and has > some difference with AM43x). Then power domain, clock domain for AM43x > is added and finally AM335x hwmod database is updated with AM43x > specifics. > > This series is being developed with additional clock tree changes that > are being DT'fied. > > Additional DTS changes (posted separate from this series) are also > required for hwmod to get register target address space as most of > AM335x hwmod address space details has been recently cleaned up and > moved to DTS. > > Regards > Afzal > > Afzal Mohammed (8): > ARM: OMAP2+: hwmod: AM335x: prepare for AM43x reuse > ARM: OMAP2+: hwmod: AMx3: runtime AM335x handling > ARM: OMAP2+: hwmod: AMx3: remove common static fields > ARM: OMAP2+: PRCM: AM43x definitions > ARM: OMAP2+: hwmod: AMx3: runtime AM43x handling > ARM: OMAP2+: hwmod: AM43x operations > ARM: OMAP2+: AM43x: PRCM kbuild > ARM: OMAP2+: hwmod: AM43x: new w.r.t AM335x > > Ambresh K (3): > ARM: OMAP2+: PM: AM43x powerdomain data > ARM: OMAP2+: CM: AM43x clockdomain data > ARM: OMAP2+: AM43x PRCM init > > Ankur Kishore (1): > ARM: OMAP2+: CM: cm_inst offset s16->u16 > > Vaibhav Bedia (1): > ARM: OMAP2+: CM: reintroduce SW_SLEEP for OMAP4 > > arch/arm/mach-omap2/Makefile | 5 +- > arch/arm/mach-omap2/clockdomain.h | 4 +- > arch/arm/mach-omap2/clockdomains43xx_data.c | 199 ++++++++ > arch/arm/mach-omap2/cm33xx.c | 30 +- > arch/arm/mach-omap2/cm33xx.h | 28 +- > arch/arm/mach-omap2/cminst44xx.c | 58 ++- > arch/arm/mach-omap2/cminst44xx.h | 25 +- > arch/arm/mach-omap2/io.c | 6 + > arch/arm/mach-omap2/omap_hwmod.c | 8 + > arch/arm/mach-omap2/omap_hwmod_33xx_data.c | 691 +++++++++++++++++++++++---- > arch/arm/mach-omap2/powerdomain.h | 1 + > arch/arm/mach-omap2/powerdomains43xx_data.c | 145 ++++++ > arch/arm/mach-omap2/prcm43xx.h | 141 ++++++ > 13 files changed, 1198 insertions(+), 143 deletions(-) > create mode 100644 arch/arm/mach-omap2/clockdomains43xx_data.c > create mode 100644 arch/arm/mach-omap2/powerdomains43xx_data.c > create mode 100644 arch/arm/mach-omap2/prcm43xx.h > > -- > 1.7.9.5 > -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
