      ARM: OMAP2/3: VENC hwmods: Remove OCPIF_SWSUP_IDLE flag from VENC slave interface · 1f5e6247
      Archit Taneja 提交于
      The clocks for all DSS slave interfaces were recently changed to "dss_ick" on
      OMAP2 and OMAP3, this clock can be autoidled by PRCM. The VENC interface
      previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and
      hence the OCPIF_SWSUP_IDLE flag was needed.
      
      Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is
      now "dss_ick".  This allows the PRCM hardware to autoidle the VENC
      interface clocks when they are not active, rather than relying on the
      software to do it, which can keep the interface clocks active
      unnecessarily.

      ARM: OMAP2+: hwmod: Revert "ARM: OMAP2+: hwmod: Make omap_hwmod_softreset wait for reset status" · 3c55c1ba
      Paul Walmsley 提交于
      This reverts commit f9a2f9c3.  This
      commit caused a regression in the I2C hwmod reset on OMAP2/3/4,
      logging messages similar to these during boot:
      
      [    0.200378] omap_hwmod: i2c1: softreset failed (waited 10000 usec)
      [    0.222076] omap_hwmod: i2c2: softreset failed (waited 10000 usec)
      
      While the original patch was intended to fix some reset-related timing
      issues, it's believed that these problems were actually fixed by
      commit 2800852a ("ARM: OMAP2+: hwmod:
      Restore sysc after a reset"):

      ARM: OMAP2+: hwmod: add softreset delay field and OMAP4 data · d99de7f5
      Fernando Guzman Lugo 提交于
      Due to HW limitation, some IPs should not be accessed just after a
      softreset. Since the current hwmod sequence is accessing the sysconfig
      register just after the reset, it might lead to OCP bus error in
      that case.
      
      Add a new field in the sysconfig structure to specify a delay in usecs
      needed after doing a softreset.
      
      In the case of the ISS and FDIF modules, the L3 OCP port will be
      disconnected upon a SW reset. That issue was confirmed with HW simulation
      and an errata should be available soon. The HW recommendation to avoid
      that is to wait for 100 OCP clk cycles, before accessing the IP.
      
      Considering the worse case (OPP50), the L3 bus will run at 100 MHz,
      so a 1 usec delay is needed. Add an x2 margin to be safe.

      ARM: OMAP2+: OPP: allow OPP enumeration to continue if device is not present · 9fa2df6b
      Nishanth Menon 提交于
      On platforms such as OMAP3, certain variants may not have IVA, SGX
      or some specific component. We currently have a check to aid fixing
      wrong population of OPP entries for issues such as typos. This however
      causes a conflict with valid requirement where the SoC variant does
      not actually have the module present.
      
      So, reduce the severity of the print to a debug statement and skip
      registering that specific OPP, but continue down the list.

      ARM: OMAP4: Workaround the OCP synchronisation issue with 32K synctimer. · 68523f42
      Santosh Shilimkar 提交于
      On OMAP4, recently a synchronisation bug is discovered by hardware
      team, which leads to incorrect timer value read from 32K sync timer
      IP when the IP is comming out of idle.
      
      The issue is due to the synchronization methodology used in the SYNCTIMER IP.
      The value of the counter register in 32kHz domain is synchronized to the OCP
      domain register only at count up event, and if the OCP clock is switched off,
      the OCP register gets out of synch until the first count up event after the
      clock is switched back -at the next falling edge of the 32kHz clock.
      
      Further investigation revealed that it applies to gptimer1 and watchdog timer2
      as well which may run on 32KHz. This patch fixes the issue for all the
      applicable modules.
      
      The BUG has not made it yet to the OMAP errata list and it is applicable to
      OMAP1/2/3/4/5. OMAP1/2/3 it is taken care indirectly by autodeps.
      
      By enabling static depedency of wakeup clockdomain with MPU, as soon as MPU
      is woken up from lowpower state(idle) or whenever MPU is active, PRCM forces
      the OCP clock to be running and allow the counter value to be updated properly
      in the OCP clock domain.
      
      The bug is going to fixed in future OMAP versions.
