This patch series carries some miscellaneous
OMAP driver fixes for GPIO and UART drivers.

For GPIO, add gpio_enable and gpio_disable calls
to gpio-omap which fixes an issue where if there
is an irq storm, serial console is unresponsive.

For UART, move pm_runtime_get_sync since the
current order of omap_8250_rx_dma_flush and
pm_runtime_get_sync calls are set in a way that
when omap_8250_shutdown returns, dma->rx_running
is set and this causes issues next time the UART
is re-opened.

Changes since v1:
- Fix CC list
- Drop Fixes tag

Judith Mendez (2):
  gpio: omap: Add omap_gpio_disable/enable_irq calls
  serial: 8250: omap: Move pm_runtime_get_sync

Could you summarize which OMAP platforms this was tested on?

Thanks,
