* [PATCH 3/5] ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architecture 2012-03-26 11:43 ` Viresh Kumar @ 2012-03-26 11:43 ` Viresh Kumar -1 siblings, 0 replies; 12+ messages in thread From: Viresh Kumar @ 2012-03-26 11:43 UTC (permalink / raw) To: linux-arm-kernel Cc: devicetree-discuss, arnd, spear-devel, viresh.linux, sr, plagnioj This patch adds a generic target for SPEAr3xx machines that can be configured via the device-tree. Currently the following devices are supported via the devicetree: - VIC interrupts - PL011 UART - PL061 GPIO - PL110 CLCD - SP805 WDT - Synopsys DW I2C - Synopsys DW ethernet - ST FSMC-NAND - ST SPEAR-SMI - ST SPEAR-KEYBOARD - ST SPEAR-RTC - ARASAN SDHCI-SPEAR - SPEAR-EHCI - SPEAR-OHCI Other peripheral devices will follow in later patches.

* [PATCH 3/5] ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architecture @ 2012-03-26 11:43 ` Viresh Kumar 0 siblings, 0 replies; 12+ messages in thread From: Viresh Kumar @ 2012-03-26 11:43 UTC (permalink / raw) To: linux-arm-kernel This patch adds a generic target for SPEAr3xx machines that can be configured via the device-tree. Currently the following devices are supported via the devicetree: - VIC interrupts - PL011 UART - PL061 GPIO - PL110 CLCD - SP805 WDT - Synopsys DW I2C - Synopsys DW ethernet - ST FSMC-NAND - ST SPEAR-SMI - ST SPEAR-KEYBOARD - ST SPEAR-RTC - ARASAN SDHCI-SPEAR - SPEAR-EHCI - SPEAR-OHCI Other peripheral devices will follow in later patches.
