2017-03-28ARM: OMAP2+: dm81xx: Add clkdm and hwmod for SATAKevin Hilman

2017-03-28ARM: DRA7: hwmod_data: Prevent wait_target_disable error for usb_otg_ssRoger Quadros
It seems that if L3_INIT clkdomain is kept in HW_AUTO while usb_otg_ss is in use then there are random chances that the usb_otg_ss module will fail to completely idle. i.e. IDLEST = 0x2 instead of 0x3. Preventing L3_INIT from HW_AUTO while usb_otg_ss module is in use fixes this issue. We don't know yet if usb_otg_ss instances 3 and 4 are affected by this issue or not so don't add this flag for those instances.

2017-03-27ARM: omap2+: Revert omap-smp.c changes resetting CPU1 during bootTony Lindgren
Commit 3251885285e1 ("ARM: OMAP4+: Reset CPU1 properly for kexec") started unconditionally resetting CPU1 because of a kexec boot issue I was seeing earlier on omap4 when doing kexec boot between two different kernel versions. This caused issues on some systems. We should only reset CPU1 as a last resort option, and try to avoid it where possible. Doing an unconditional CPU1 reset causes issues for example when booting a bootloader configured secure OS running on CPU1 as reported by Andrew F. Davis <afd@ti.com>. We can't completely remove the reset of CPU1 as it would break kexec booting from older kernels. But we can limit the CPU1 reset to cases where CPU1 is wrongly parked within the memory area used by the booting kernel. Then later on we can add support for parking CPU1 for kexec out of the SDRAM back to bootrom. So let's first fix the regression reported by Andrew by making CPU1 reset conditional. To do this, we need to: 1. Save configured AUX_CORE_BOOT_1 for later 2. Modify AUX_CORE_BOOT_0 reading code to for HS SoCs to return the whole register instead of the CPU mask 3. Check if CPU1 is wrongly parked into the booting kernel by the previous kernel and reset if needed Fixes: 3251885285e1 ("ARM: OMAP4+: Reset CPU1 properly for kexec") Reported-by: Andrew F.

2017-03-23ARM: OMAP2+ hwmod: Allow modules to disable HW_AUTORoger Quadros
Introduce HWMOD_CLKDM_NOAUTO flag that allows the hwmod's clockdomain to be prevented from HW_AUTO while the hwmod is active.

2017-03-14ARM: OMAP2+: Remove mostly unused hwmod linkspaceTony Lindgren
We want to be able to dynamically allocate struct omap_hwmod_ocp_if and struct omap_hwmod at device driver probe time based on .dts data. Current setup with the linkspace using memblock_virt_alloc() makes this tricky, so let's get rid of struct linkspace and directly set up struct omap_hwmod_ocp_if as the master and slave lists. As we are currently not using the master_ports either, let's remove it too. And let's add the struct omap_hwmod_ocp_if node directly to the slave_ports list.

2017-03-08clk: ti: convert to use proper register definition for all accessesTero Kristo
Currently, TI clock driver uses an encapsulated struct that is cast into a void pointer to store all register addresses. This can be considered as rather nasty hackery, and prevents from expanding the register address field also. Instead, replace all the code to use proper struct in place for this, which contains all the previously used data. This patch is rather large as it is touching multiple files, but this can't be split up as we need to avoid any boot breakage.

The commit referenced above exposes this problem. To fix the problem, use of_get_child_by_name() instead of of_find_node_by_name(); of_get_child_by_name() does not drop the reference count of passed device nodes. While semantically different, we only look for immediate children of the passed device node, so of_get_child_by_name() is a more appropriate function to use anyway. Release the reference to the device node obtained with of_get_child_by_name() after it is no longer needed to avoid another device node leak. While at it, clean up the code and change the return type of omap3xxx_hwmod_is_hs_ip_block_usable() to bool to match its use and the return type of of_device_is_available().

Also updates the users of dev_pm_opp_find_freq_*() routines to call dev_pm_opp_put() after they are done using the OPPs.

2017-01-20ARM: OMAP2+: omap_hwmod: Add support for earlyconLokesh Vutla
Hwmod core tries to reset and idles each IP that is registered with hwmod. In case of earlycon, that specific uart IP cannot be reset or keep it in idle state else earlycon hangs once hwmod resets that uart IP. So add support to not reset uart that is being used as earlycon only if CONFIG_SERIAL_EARLYCON is enabled.

2017-01-20ARM: OMAP3: Fix SoC detection of OMAP36/37 FamilyAdam Ford
The OMAP36/37 families are similar, but there are a few features sections that can help identify some of them. Let's add checks for 3630/3730, OMAP3621, DM3725, OMAP3615/DM3715, OMAP3611, and AM3703 all based on features similar to what was done for the OMAP34xx/35xx series The checkpatch flags some warnings for braces, but I kept the coding style to match the adjacent code for consistency. I don't have an OMAP36xx to test, but this was tested on both a DM3730 and AM3703. Signed-off-by: Adam Ford <aford173@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2017-01-20ARM: OMAP5: Add HWMOD_SWSUP_SIDLE_ACT flag for UARTVignesh R
According to the commit ca43ea345de9 ("ARM: OMAP2+: hwmod: Add a new flag to handle SIDLE in SWSUP only in active"), UART IP needs the sidle mode to be controlled in SW only while they are active. Once inactive, the IP needs to be put back in HW control so they are also wakeup capable. The flag HWMOD_SWSUP_SIDLE takes care of this. So add this flag to all instances of UART. With this change, 8250 UART now gives out proper RX Timeout interrupts and is usable as console.

2016-12-27ARM: omap2+: am437x: rollback to use omap3_gptimer_timer_init()Grygorii Strashko
The commit 55ee7017ee31 ("arm: omap2: board-generic: use omap4_local_timer_init for AM437x") unintentionally changes the clocksource devices for AM437x from OMAP GP Timer to SyncTimer32K. Unfortunately, the SyncTimer32K is starving from frequency deviation as mentioned in commit 5b5c01359152 ("ARM: OMAP2+: AM43x: Use gptimer as clocksource") and, as reported by Franklin [1], even its monotonic nature is under question (most probably there is a HW issue, but it's still under investigation). Taking into account above facts It's reasonable to rollback to the use of omap3_gptimer_timer_init().
