2016-04-21net: phy: spi_ks8895: Don't leak references to SPI devicesMark Brown1-1/+1
The ks8895 driver is using spi_dev_get() apparently just to take a copy of the SPI device used to instantiate it but never calls spi_dev_put() to free it. Since the device is guaranteed to exist between probe() and remove() there should be no need for the driver to take an extra reference to it so fix the leak by just using a straight assignment.

2016-02-16net: phy: spi_ks8995: include linux/gpio/consumer.hArnd Bergmann1-1/+1
The ks8995 phy driver just started using gpiod_* functions, which are declared in linux/gpio/consumer.h, not linux/gpio.h, resulting in a build failure in randconfig builds that do not have CONFIG_GPIOLIB enabled: drivers/net/phy/spi_ks8995.c: In function 'ks8995_probe': drivers/net/phy/spi_ks8995.c:477:3: error: implicit declaration of function 'gpiod_set_value' [-Werror=implicit-function-declaration] This changes the header inclusion so it builds in all configurations.

Add support for MICREL KSZ8795CLX Integrated 5-Port, 10-/100-Managed Ethernet Switch with Gigabit GMII/RGMII and MII/RMII interfaces. Signed-off-by: Helmut Buchsbaum <helmut.buchsbaum@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-02-11net: phy: spi_ks8995: generalize creation of SPI commandsHelmut Buchsbaum1-11/+35
Prepare creating SPI reads and writes for other switch families. The KS8995 family uses the straight forward <8bit CMD><8bit ADDR> sequence. To be able to support KSZ8795 family, which uses <3bit CMD><12bit ADDR><1 bit TR> make the SPI command creation chip variant dependent.

2016-02-11net: phy: spi_ks8995: add support for resetting switch using GPIOHelmut Buchsbaum1-9/+62
When using device tree it is no more possible to reset the PHY at board level. Furthermore, doing in the driver allows to power down the switch when it is not used any more. The patch introduces a new optional property "reset-gpios" denoting an appropriate GPIO handle, e.g.: reset-gpios = <&gpio0 46 GPIO_ACTIVE_LOW> Signed-off-by: Helmut Buchsbaum <helmut.buchsbaum@gmail.com> Signed-off-by: David S.

2016-02-11net: phy: spi_ks8995: verify chip and determine revisionHelmut Buchsbaum1-38/+80

2015-07-30net: phy: spi_ks8995: clean up ks8995_registers_read/writeVladimir Zapolskiy1-22/+0
The change removes redundant sysfs binary file boundary checks, since this task is already done on caller side in fs/sysfs/file.c Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-04net: phy: spi_ks8995: remove sysfs bin file by registered attributeVladimir Zapolskiy1-1/+3
When a sysfs binary file is asked to be removed, it is found by attribute name, so strictly speaking this change is not a fix, but just in case when attribute name is changed in the driver or sysfs internals are changed, it might be better to remove the previously created file using right the same binary attribute.

2014-01-16drivers/net: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2012-04-13net: Remove redundant spi driver bus initializationLars-Peter Clausen1-1/+0
In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register() so we can drop the manual assignment.
