From: Alexander Shiyan @ 2014-07-05 5:36 UTC (permalink / raw)
To: linux-arm-kernel
Use clock definitions in i.MX27 DTS files.
Additional changes included in this patch (imx27.dtsi):
- Fix IPG clock for UART6.
- Use EMI_AHB_GATE clock for WEIM.
- Added GPIO_IPG_GATE clock for GPIO nodes. Currently this clock is
not used by the driver, but it can be added in the future.
