* RTC driver for PT7C4338 chip.Priyanka Jain2010-12-17-0/+145
| | | | | | | | | | | PT7C4338 chip is being manufactured by Pericom Technology Inc. It is a serial real-time clock which provides: 1)Low-power clock/calendar. 2)Programmable square-wave output. It has 56 bytes of nonvolatile RAM. Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Acked-by: Timur Tabi <timur@freescale.com>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <sebastien.carlier@gmail.com>

* Clean-up of s3c24x0 drivers excluding nand driverkevin.morfitt@fearnside-systems.co.uk2009-10-13-64/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch re-formats the arm920t s3c24x0 driver files, excluding the nand driver, in preparation for changes to add support for the Embest SBC2440-II Board. The changes are as follows: - re-indent the code using Lindent - make sure register layouts are defined using a C struct - replace the upper-case typedef'ed C struct names with lower case non-typedef'ed ones - make sure registers are accessed using the proper accessor functions - run checkpatch.pl and fix any error reports It assumes the following patch has been applied first: - [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009 - patches 1/4 and 2/4 of this series Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have any s3c2400 or s3c2410 boards but need this patch applying before I can submit patches for the SBC2440-II Board. Also, temporarily modified sbc2410x, smdk2400, smdk2410 and trab configs to use the mtd nand driver (which isn't used by any board at the moment), ran MAKEALL for all ARM9 targets and no new warnings or errors were found.

* i.MX31: Make the SPI bus and chip select configurable for MC13783Magnus Lilja2008-09-12-2/+4
| | | | | | | | | | | The i.MX31 has three SPI buses and each bus has several chip selects and the MC13783 chip can be connected to any of these. The current RTC driver for MC13783 is hardcoded for CSPI2/SS2. This patch makes make MC13783 SPI bus and chip select configurable via CONFIG_MC13783_SPI_BUS and CONFIG_MC13783_SPI_CS.

* Makefile: compile and link each module just onceWolfgang Denk2008-09-09-3/+3
| | | | | | | | | | | | Several source files need to be compiled and linked when one or more config options are selected. To allow for easy selection in the Makefiles yet to avoild multiple compilation (which costs build time) and especially multiple linking (which causes errors), we use "COBJS = $(sort COBJS-y)" which eliminates duplicates.

Instead of the spi_chipsel table, each board that wants to use SPI gets to implement three hooks: * spi_cs_activate(): Activates the chipselect for a given slave * spi_cs_deactivate(): Deactivates the chipselect for a given slave * spi_cs_is_valid(): Determines if the given bus/chipselect combination can be activated. Not all drivers may need those extra functions however. If that's the case, the board code may just leave them out (assuming they know what the driver needs) or rely on the linker to strip them out (assuming --gc-sections is being used.) To set up communication parameters for a given slave, the driver needs to call spi_setup_slave(). This returns a pointer to an opaque spi_slave struct which must be passed as a parameter to subsequent SPI calls. This struct can be freed by calling spi_free_slave(), but most driver probably don't want to do this. Before starting one or more SPI transfers, the driver must call spi_claim_bus() to gain exclusive access to the SPI bus and initialize the hardware. When all transfers are done, the driver must call spi_release_bus() to make the bus available to others, and possibly shut down the SPI controller hardware. spi_xfer() behaves mostly the same as before, but it now takes a spi_slave parameter instead of a spi_chipsel function pointer. It also got a new parameter, flags, which is used to specify chip select behaviour. This may be extended with other flags in the future. This patch has been build-tested on all powerpc and arm boards involved. I have not tested NIOS since I don't have a toolchain for it installed, so I expect some breakage there even though I've tried fixing up everything I could find by visual inspection. I have run-time tested this on AVR32 ATNGW100 using the atmel_spi and DataFlash drivers posted as a follow-up. I'd like some help testing other boards that use the existing SPI API. But most of all, I'd like some comments on the new API. Is this stuff usable for everyone? If not, why? Changed in v4: - Build fixes for various boards, drivers and commands - Provide common struct spi_slave definition that can be extended by drivers - Pass a struct spi_slave * to spi_cs_activate and spi_cs_deactivate - Make default bus and mode build-time configurable - Override default SPI bus ID and mode on mx32ads and imx31_litekit. Changed in v3: - Add opaque struct spi_slave for controller-specific data associated with a slave. - Add spi_claim_bus() and spi_release_bus() - Add spi_free_slave() - spi_setup() is now called spi_setup_slave() and returns a struct spi_slave - soft_spi now supports four SPI modes (CPOL|CPHA) - Add bus parameter to spi_setup_slave() - Convert the new i.MX32 SPI driver - Convert the new MC13783 RTC driver Changed in v2: - Convert the mpc8xxx_spi driver and the mpc8349emds board to the new API.
