reset: brcmstb: Enable reset drivers for ARCH_BCM2835

2025-08-28T14:28:18+00:00

[ Upstream commit 1d99f92f71b6b4b2eee776562c991428490f71ef ]

The BRCMSTB and BRCMSTB_RESCAL reset drivers are also
used in the BCM2712, AKA the RPi5. The RPi platforms
have typically used the ARCH_BCM2835, and the PCIe
support for this SoC can use this config which depends
on these drivers so enable building them when just that
arch option is enabled to ensure the platform works as
expected.

reset: starfive: jh71x0: Fix accessing the empty member on JH7110 SoC

2025-04-07T08:06:36+00:00

commit 2cf59663660799ce16f4dfbed97cdceac7a7fa11 upstream.

data->asserted will be NULL on JH7110 SoC since commit 82327b127d41
("reset: starfive: Add StarFive JH7110 reset driver") was added. Add
the judgment condition to avoid errors when calling reset_control_status
on JH7110 SoC.

[ Upstream commit b14e40f5dc7cd0dd7e958010e6ca9ad32ff2ddad ]

Driver is leaking OF node reference on memory allocation failure.
Acquire the OF node reference after memory allocation to fix this and
keep it simple.

reset: Fix crash when freeing non-existent optional resets

2024-01-01T12:42:26+00:00

[ Upstream commit 4a6756f56bcf8e64c87144a626ce53aea4899c0e ]

When obtaining one or more optional resets, non-existent resets are
stored as NULL pointers, and all related error and cleanup paths need to
take this into account.

Currently only reset_control_put() and reset_control_bulk_put()
get this right.  All of __reset_control_bulk_get(),
of_reset_control_array_get(), and reset_control_array_put() lack the
proper checking, causing NULL pointer dereferences on failure or
release.

Fix this by moving the existing check from reset_control_bulk_put() to
__reset_control_put_internal(), so it applies to all callers.
The double check in reset_control_put() doesn't hurt.

Pull clk subsystem updates from Stephen Boyd:
 "This pull request is full of clk driver changes. In fact, there aren't
  any changes to the clk framework this time around. That's probably
  because everyone was on vacation (yours truly included). We did lose a
  couple clk drivers this time around because nobody was using those
  devices. That skews the diffstat a bit, but either way, nothing looks
  out of the ordinary here. The usual suspects are chugging along adding
  support for more SoCs and fixing bugs.

  If I had to choose, I'd say the theme for the past few months has been
  "polish". There's quite a few patches that migrate to
  devm_platform_ioremap_resource() in here. And there's more than a
  handful of patches that move the NR_CLKS define from the DT binding
  header to the driver. There's even patches that migrate drivers to use
  clk_parent_data and clk_hw to describe clk tree topology. It seems
  that the spring (summer?) cleaning bug got some folks, or the
  semiconductor shortage finally hit the software side.

  New Drivers:
   - StarFive JH7110 SoC clock drivers
   - Qualcomm IPQ5018 Global Clock Controller driver
   - Versa3 clk generator to support 48KHz playback/record with audio
     codec on RZ/G2L SMARC EVK

  Removed Drivers:
   - Remove non-OF mmp clk drivers
   - Remove OXNAS clk driver

  Updates:
   - Add __counted_by to struct clk_hw_onecell_data and struct
     spmi_pmic_div_clk_cc
   - Move defines for numbers of clks (NR_CLKS) from DT headers to
     drivers
   - Introduce kstrdup_and_replace() and use it
   - Add PLL rates for Rockchip rk3568
   - Add the display clock tree for Rockchip rv1126
   - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and
     RZ/G2 SoCs
   - Convert sun9i-mmc clock to use
     devm_platform_get_and_ioremap_resource()
   - Fix function name in a comment in ccu_mmc_timing.c

   - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e.
     consider alternative parent rates when determining clock rates
   - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
   - Support finding closest (as opposed to closest but not higher)
     clock rate for NM, NKM, mux and div type clocks, as use it for
     Allwinner A64 pll-video0
   - Prefer current parent rate if able to generate ideal clock rate for
     Allwinner NKM clocks
   - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks
     moved out to the interconnect drivers
   - Fix various PM runtime bugs across many Qualcomm clk drivers
   - Migrate Qualcomm MDM9615 is to parent_hw and parent_data
   - Add network related resets on Qualcomm IPQ4019

     clock controller driver
   - Support retention for the Qualcomm SC8280XP display clock
     controller GDSCs.

     to fix issues with missing parent clocks across sc7180, sm7150,
     sm6350 and sm8250, while sm8450 is corrected to use floor ops

   - Drop restrictions for i.MX PLL14xx and fix its max prediv value
   - Drop the 393216000 and 361267200 from i.MX PLL14xx rate table to
     allow glitch free switching"

reset: ti: syscon: remove unneeded call to platform_set_drvdata()

2023-08-08T13:31:00+00:00

This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver. Also,
the private data is defined in this driver, so there is no risk of it being
accessed outside of this driver file.
