omap: Don't use gpio_free to change direction to input

2011-10-27T19:56:35Z

gpio_free() should not have the side effect of setting the line to input since this prevents the gpio command from being able to set a line as output. Signed-off-by: Joe Hershberger Cc: Joe Hershberger Cc: Sandeep Paulraj Signed-off-by: Sandeep Paulraj

OMAP3: overo: Move ethernet CS4 configuration to execute based on board id

2011-10-27T19:56:35Z

By moving the CS4 configuration into the board specific configuration, it is left free for custom carrier boards. The USRP-E1XX series uses CS4 to control access to an FPGA, so without this patch the device driver cannot claim CS4.

omap: overo: Disable pull-ups on camera PCLK, HS and VS signals

2011-10-27T19:56:34Z

The level shifters used on the Caspa camera module have a 4k output impedance. Combined with the 100uA pull-up resistors in the OMAP3, this raises the ground level to 400mV. Adding crosstalk between the pixel clock and the HS/VS signals on the flat cable (a ground line in between would have been nice), logic 0 levels can raise up to 650mV. This exceeds the camera input pins VIL maximum voltage. This change suggested-by Laurent Pinchart Signed-off-by: Steve Sakoman Signed-off-by: Sandeep Paulraj

omap: overo: Configure mux for gpio10

2011-10-27T19:56:34Z

This pad was previously configured for sysclkout_1. This patch changes the configuration to gpio_10 to reduce radiated noise from the 26Mhz clock, as well as make the pin more generally useful. Signed-off-by: Steve Sakoman Acked-by: Philip Balister Signed-off-by: Sandeep Paulraj

punt unused clean/distclean targets

2011-10-15T20:20:36Z

The top level Makefile does not do any recursion into subdirs when cleaning, so these clean/distclean targets in random arch/board dirs never get used. Punt them all. MAKEALL didn't report any errors related to this that I could see. Signed-off-by: Mike Frysinger

overo: Set IEN on GPMC_CLK to support synchronous clocking.

2011-09-30T20:00:53Z

Without this change CS's configured for synchronous clocking cannot read data. Signed-off-by: Philip Balister Signed-off-by: Sandeep Paulraj

OMAP3: Overo: Update GPMC timing for ethernet chip

2011-09-30T20:00:53Z

The existing timing does not quite meet the minimum requirements in the LAN9221 datasheet. The timing in this patch solves problems noticed on some parts. The patch also combines the CS configuration for the overo and igep0020 boards per request. Signed-off-by: Philip Balister Signed-off-by: Sandeep Paulraj

omap: gpio: Adapt board files to use generic API

2011-09-13T06:25:15Z

This patch contains updates the sources in the board files to use the generic API. Signed-off-by: Sanjeev Premi

Move DECLARE_GLOBAL_DATA_PTR to file scope

2010-12-21T10:33:36Z

It can be optimised out by the compiler otherwise resulting in obscure errors like a board not booting. This has been documented in README since 2006 when these were first fixed up for GCC 4.x. Signed-off-by: John Rigby Fix some additional places. Signed-off-by: Wolfgang Denk Acked-By: Albert ARIBAUD

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier
