2011-03-14OMAP2+: Common CPU DIE ID reading code reads wrong registers for OMAP4430Andy Green
This adapts the register offsets used to read the CPU DIE ID registers when run on 44XX so they match what is in the OMAP4430 Reference Manual page 269 Signed-off-by: Andy Green <andy.green@linaro.org> Signed-off-by: Tony Lindgren <tony@atomide.com>
2011-02-17omap: Add chip id recognition for OMAP4 ES2.1 and ES2.2Nishant Kamat
Allow OMAP4 ES2.1 and ES2.2 revisions to be recognized in the omap4_check_revision() function. Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz). ES2.2 additionally has a couple of power management fixes (to reduce leakage), an I2C1 SDA line state fix, and a floating point write corruption fix (cortex erratum). Even though the current mainline support doesn't need to distinguish between ES2.X versions, it's still useful to know the correct silicon rev when issues are reported. Moreover, these id checks can be used by power management code that selects suitable OPPs considering the memory speed limitation on ES2.0.

2010-10-08OMAP: control: move plat-omap/control.h to mach-omap2/control.hPaul Walmsley
Only OMAP2+ platforms have the System Control Module (SCM) IP block. In the past, we've kept the SCM header file in plat-omap. This has led to abuse - device drivers including it; includes being added that create implicit dependencies on OMAP2+ builds; etc. In response, move the SCM headers into mach-omap2/. As part of this, remove the direct SCM access from the OMAP UDC driver. It was clearly broken. The UDC code needs an indepth review for use on OMAP2+ chips.

In 3630, DPLL4M2 output can be 96MHz or 192MHz (for SGX to run at 192).

SGX can select Core Clock, 192MHz clock or CM_96M_FCLK as it's functional clock. In summary changes done are: 1. Added a feature called omap3_has_192mhz_clk and enabled for 3630 2.

For example, the CHIP_IS_OMAP2420 bit is set in omap_chip at boot on an OMAP2420. On OMAP3430ES2, both CHIP_IS_OMAP3430 and CHIP_IS_OMAP3430ES2 bits are set. omap_chip is set in mach-omap2/id.c by _set_omap_chip(). Other code should use the omap_chip_is() function to test against omap_chip.
