However, the transceiver should be powered on by default, otherwise USB doesn't work at all for networking during boot. All kernels after v3.0 are affected.

| | * ARM: OMAP2PLUS: DSS: Ensure DSS works correctly if display is enabled in ↵Archit Taneja2011-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bootloader Resetting DISPC when a DISPC output is enabled causes the DSS to go into an inconsistent state. Thus if the bootloader has enabled a display, the hwmod code cannot reset the DISPC module just like that, but the outputs need to be disabled first. Add function dispc_disable_outputs() which disables all active overlay manager and ensure all frame transfers are completed. Modify omap_dss_reset() to call this function and clear DSS_CONTROL, DSS_SDI_CONTROL and DSS_PLL_CONTROL so that DSS is in a clean state when the DSS2 driver starts. This resolves the hang issue(caused by a L3 error during boot) seen on the beagle board C3, which has a factory bootloader that enables display. The issue is resolved with this patch. Thanks to Tomi and Sricharan for some additional testing.

| | * ARM: OMAP: HWMOD: Unify DSS resets for OMAPsTomi Valkeinen2011-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a custom DSS reset function used on OMAPs from OMAP2 forward. The function doesn't actually do a reset, it only waits for the reset to complete. The reason for this is that on OMAP4 there is no possibility to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets all the other DSS modules also, thus breaking the HWMOD model where every DSS module is handled independently. This fixes the problem with DSS reset on OMAP4, caused by the fact that because there's no SW reset for dss_core on OMAP4, the HWMOD framework doesn't try to reset dss_core and thus the DSS clocks were never enabled at the same time. This causes causes the HWMOD reset to fail for dss_dispc and dss_rfbi. The common reset function will also allow us to fix another problem in the future: before doing a reset we need to disable DSS outputs, which are in some cases enabled by the bootloader, as otherwise DSS HW seems to get more or less stuck, requiring a power reset to recover.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OMAP4 HWMOD data currently contains errors with DSS clocks: dss_hdmi and dss_venc have their main_clks wrong. The clocks should be dss_48mhz_clk and dss_tv_clk, respectively. These problems were temporarily fixed with the DSS patches 9ede365aa6f74428a1f69c21ca1cf21213167576 ("HACK: OMAP: DSS2: clk hack for OMAP2/3"), and df5d3ed23cf73ee0763a8963003bda9b69d9620f ("OMAP: DSS2: HDMI: fix hdmi clock name"), which can be reverted after this patch.

| | * ARM: OMAP4: HWMOD: Add HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_coreTomi Valkeinen2011-11-08

Before v3.1-rc1 the omapdss driver was managing clocks and resets correctly. However, when omapdss started using runtime PM at v3.1-rc1, the responsibility for the reset moved to HWMOD framework. HWMOD framework does not currently enable all the DSS clocks when resetting the DSS hardware. This causes the HWMOD frameworks boot-time reset to fail, possibly leaving the DSS hardware in undefined state. This patch sets HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core. The flag is actually not used on OMAP4, because dss_core hardware does not have soft-reset functionality and thus the HWMOD framework never resets nor waits for the reset to finish. However, while the flag is not strictly needed currently, I think it represents the HW correctly: all the DSS clocks should be enabled after power-on to allow DSS hardware to finish its reset. A custom reset function will be added in the following patches which manages this correctly for OMAP4.

However, zero is also returned when context has never been lost and could also be returned when the context loss count has wrapped and goes to zero. Change the functions to return an int, with negative value meaning an error. OMAP HSMMC code uses omap_pm_get_dev_context_loss_count(), but as the hsmmc code handles the returned value as an int, with negative value meaning an error, this patch actually fixes hsmmc code also.

Currently, I/O wakeup is marked as present for all OMAP3 SoCs other than the AM3505/3517. The TI81xx family of SoCs are at present considered to be OMAP3 SoCs, but don't support I/O wakeup. To resolve this, convert the existing blacklist approach to an explicit, whitelist support, in which only SoCs which are known to support I/O wakeup are listed. (At present, this only includes OMAP34xx, OMAP3503, OMAP3515, OMAP3525, OMAP3530, and OMAP36xx.) Also, the current code incorrectly detects the presence of a software-controllable I/O chain clock on several chips that don't support it. This results in writes to reserved bitfields, unnecessary delays, and console messages on kernels running on those chips: http://www.spinics.net/lists/linux-omap/msg58735.html Convert this test to a feature test with a chip-by-chip whitelist.

ABE_FCLK --> AESS_FCLK --> OCP_ABE_ICLK The AESS_FCLK and OCP_ABE_ICLK clocks both have dividers which determine their operational frequency. However, the dividers for the AESS_FCLK and OCP_ABE_ICLK are controlled via a single bit, which is the CM1_ABE_AESS_CLKCTRL[24] bit. When this bit is set to 0, the AESS_FCLK divider is 1 and the OCP_ABE_ICLK divider is 2. Similarly, when this bit is set to 1, the AESS_FCLK divider is 2 and the OCP_ABE_ICLK is 1. The above relationship between the AESS_FCLK and OCP_ABE_ICLK dividers ensure that the OCP_ABE_ICLK clock is always half the frequency of the ABE_CLK... OCP_ABE_ICLK = ABE_FCLK/2 The divider for the OCP_ABE_ICLK is currently missing so add a divider that will ensure the OCP_ABE_ICLK frequency is always half the ABE_FCLK frequency.
