2017-01-06spi: bcm53xx: (re)license code to the GPL v2Rafał Miłecki1-1/+9
My intention was to release this code under GPL v2 license. For some reason my initial commit 0fc6a323e191 ("spi: bcm53xx: driver for SPI controller on Broadcom bcma SoC") totally missed licensing info. MODULE_LICENSE was later added by Axel specifying "GNU Public License v2 or later". This patch clarifies situation by adding a proper header (with Copyright line) and adjusting MODULE_LICENSE. It should be acked by every driver contributor.

2016-12-31spi: bcm53xx: set of_node to let DT specify device(s)Rafał Miłecki1-7/+1
Setting of_node of master's dev seems to be a common way of letting it work nicely with DT. This allows specifying device there instead of hardcoding one in the driver code. This was successfully tested with commit 1b47b98acce2 ("ARM: BCM5301X: Add DT entry for SPI controller and NOR flash") Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-04-18spi: bcm53xx: add spi_flash_read callback for MMIO-based readsRafał Miłecki1-2/+76
This implements more efficient reads of SPI-attached flash content. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-09-16spi: bcm53xx: Adjust devm usageVaishali Thakkar1-11/+2
Remove use of spi_unregister_master in remove function as devm_spi_register_master in probe function automatically handles it. To be compatible with the change, use direct return instead of goto and remove unnedded label out. Also, remove bcm53xxspi_bcma_remove as it is now redundant.

Use the normal {} instead of a macro to terminate an array. Remove the macro too. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-02-11spi: bcm53xx: use msecs_to_jiffies for conversionNicholas Mc Guire1-2/+2
Converting milliseconds to jiffies by "val * HZ / 1000" is technically ok but msecs_to_jiffies(val) is the cleaner solution and handles all corner cases correctly. This is only an API consolidation and should make things more readable Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-08-19spi: bcm53xx: driver for SPI controller on Broadcom bcma SoCRafał Miłecki1-0/+295
Broadcom 53xx ARM SoCs use bcma bus that contains various cores (AKA devices). If board has a serial flash, it's connected over SPI and the bcma bus includes a SPI controller. Example log from such a board: bus0: Found chip with id 53010, rev 0x00 and package 0x02 (...) bus0: Core 18 found: SPI flash controller (manuf 0x4BF, id 0x50A, rev 0x01, class 0x0) This patch adds a bcma driver for SPI core, it registers SPI master controller and "bcm53xxspiflash" SPI device.
