      pinctrl: visconti: PINCTRL_TMPV7700 should depend on ARCH_VISCONTI · c6662da8
      Geert Uytterhoeven authored
      The Toshiba Visconti TMPV7700 series pin controller is only present on
      Visconti SoCs.  Hence add a dependency on ARCH_VISCONTI, to prevent
      asking the user about this driver when configuring a kernel without
      Visconti platform support.

      pinctrl: mediatek: Free eint data on failure · db751578
      Enric Balletbo i Serra authored
      The pinctrl driver can work without the EINT resource, but, if it is
      expected to have this resource but the mtk_build_eint() function fails
      after allocating their data (because can't get the resource or can't map
      the irq), the data is not freed and you end with a NULL pointer
      dereference. Fix this by freeing the data if mtk_build_eint() fails, so
      pinctrl still works and doesn't hang.
      
      This is noticeable after commit f97dbf48 ("irqchip/mtk-sysirq: Convert
      to a platform driver") on MT8183 because, due this commit, the pinctrl driver
      fails to map the irq and spots the following bug:

      intel-pinctrl for v5.10-1
      
      * Add last part of cleanup Cherryview driver to align with other drivers
      * Due to above clean up Cherryview and Baytrail drivers to use common API
      
      The following is an automated git shortlog grouped by driver:
      
      baytrail:
       -  Switch to use intel_pinctrl_get_soc_data()
      
      cherryview:
       -  Preserve CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOs
       -  Switch to use intel_pinctrl_get_soc_data()
       -  Utilize temporary variable to hold device pointer
       -  Switch to use struct intel_pinctrl
       -  Move custom community members to separate data struct
       -  Drop stale comment
      
      intel:
       -  Update header block to reflect direct dependencies
       -  Extract intel_pinctrl_get_soc_data() helper for wider use
