This is essentially a linear encoding ++ * of a nondeterministic finite-state machine (aka syntax charts or ++ * "railroad normal form" in parsing technology). Each node is an opcode ++ * plus a "next" pointer, possibly plus an operand. "Next" pointers of ++ * all nodes except BRANCH implement concatenation; a "next" pointer with ++ * a BRANCH on both ends of it is connecting two alternatives. (Here we ++ * have one of the subtle syntax dependencies: an individual BRANCH (as ++ * opposed to a collection of them) is never concatenated with anything ++ * because of operator precedence.) The operand of some types of node is ++ * a literal string; for others, it is a node leading into a sub-FSM. In ++ * particular, the operand of a BRANCH node is the first node of the branch. ++ * (NB this is *not* a tree structure: the tail of the branch connects ++ * to the thing following the set of BRANCHes.) The opcodes are: ++ */ ++ ++/* definition number opnd? meaning */ ++#define END 0 /* no End of program. */ ++#define BOL 1 /* no Match "" at beginning of line. */ ++#define EOL 2 /* no Match "" at end of line. */ ++#define ANY 3 /* no Match any one character. */ ++#define ANYOF 4 /* str Match any character in this string. */ ++#define ANYBUT 5 /* str Match any character not in this string. */ ++#define BRANCH 6 /* node Match this alternative, or the next... */ ++#define BACK 7 /* no Match "", "next" ptr points backward. */ ++#define EXACTLY 8 /* str Match this string. */ ++#define NOTHING 9 /* no Match empty string. */ ++#define STAR 10 /* node Match this (simple) thing 0 or more times. */ ++#define PLUS 11 /* node Match this (simple) thing 1 or more times. */ ++#define OPEN 20 /* no Mark this point in input as start of #n. */ ++ /* OPEN+1 is number 1, etc. */ ++#define CLOSE 30 /* no Analogous to OPEN. */ ++ ++/* ++ * Opcode notes: ++ * ++ * BRANCH The set of branches constituting a single choice are hooked ++ * together with their "next" pointers, since precedence prevents ++ * anything being concatenated to any individual branch. The ++ * "next" pointer of the last BRANCH in a choice points to the ++ * thing following the whole choice. This is also where the ++ * final "next" pointer of each individual branch points; each ++ * branch starts with the operand node of a BRANCH node. ++ * ++ * BACK Normal "next" pointers all implicitly point forward; BACK ++ * exists to make loop structures possible. ++ * ++ * STAR,PLUS '?', and complex '*' and '+', are implemented as circular ++ * BRANCH structures using BACK.

See the docbook-style ++documentation in the header file for more information on the struct fields. ++ ++Then allocate a new instance of a platform device by doing: ++ ++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id()); ++ ++This will allocate the platform device data structures and hook it up to the ++gpiommc driver. ++Then add the gpiommc_platform_data to the platform device. ++ ++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data)); ++ ++You may free the local instance of struct gpiommc_platform_data now. (So the ++struct may be allocated on the stack, too). ++Now simply register the platform device. ++ ++ err = platform_device_add(pdev); ++ ++Done. The gpiommc probe routine will be invoked now and you should see a kernel ++log message for the added device. ++ ++ ++Registering devices via configfs ++================================ ++ ++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example ++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded ++hardware are a common situation. ++So we provide a dynamic interface to conveniently handle adding and removing ++devices from userspace, without the need to recompile the kernel. ++ ++The "gpiommc" subdirectory at the configfs mountpoint is used for handling ++the dynamic configuration. ++ ++To create a new device, it must first be allocated with mkdir. ++The following command will allocate a device named "my_mmc": ++ mkdir /config/gpiommc/my_mmc ++ ++There are several configuration files available in the new ++/config/gpiommc/my_mmc/ directory: ++ ++gpio_data_in = The SPI data-IN GPIO pin number. ++gpio_data_out = The SPI data-OUT GPIO pin number. ++gpio_clock = The SPI Clock GPIO pin number. ++gpio_chipselect = The SPI Chipselect GPIO pin number. ++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH. ++ If 1, Chipselect is active-LOW. ++spi_mode = The SPI data mode. Can be 0-3. ++spi_delay = Enable all delays in the lowlevel bitbanging. ++max_bus_speed = The maximum SPI bus speed. In Hertz. ++ ++register = Not a configuration parameter. ++ Used to register the configured card ++ with the kernel. ++ ++The device must first get configured and then registered by writing "1" to ++the "register" file. ++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock" ++and "gpio_chipselect" are essential and _must_ be configured before writing ++"1" to the "register" file. The registration will fail, otherwise. ++ ++The default values for the other parameters are: ++gpio_chipselect_activelow = 1 (CS active-LOW) ++spi_mode = 0 (SPI_MODE_0) ++spi_delay = 1 (enabled) ++max_bus_speed = 5000000 (5 Mhz) ++ ++Configuration values can not be changed after registration. To unregister ++the device, write a "0" to the "register" file. The configuration can be ++changed again after unregistering. ++ ++To completely remove the device, simply rmdir the directory ++(/config/gpiommc/my_mmc in this example). ++There's no need to first unregister the device before removing it. That will ++be done automatically. +--- a/MAINTAINERS ++++ b/MAINTAINERS +@@ -4463,6 +4463,11 @@ T: git git://linuxtv.org/anttip/media_tr + S: Maintained + F: drivers/media/usb/hackrf/ + ++GPIOMMC DRIVER ++P: Michael Buesch ++M: mb@bu3sch.de ++S: Maintained ++ + HARDWARE MONITORING + M: Jean Delvare <jdelvare@suse.de> + M: Guenter Roeck <linux@roeck-us.net> diff --git a/target/linux/generic/patches-4.0/864-gpiommc_configfs_locking.patch b/target/linux/generic/patches-4.0/864-gpiommc_configfs_locking.patch new file mode 100644 index 0000000000..92815d91f4 --- /dev/null +++ b/target/linux/generic/patches-4.0/864-gpiommc_configfs_locking.patch @@ -0,0 +1,58 @@ +The gpiommc configfs context structure needs locking, as configfs +does not lock access between files. + +--- a/drivers/mmc/host/gpiommc.c ++++ b/drivers/mmc/host/gpiommc.c +@@ -144,6 +144,8 @@ struct gpiommc_configfs_device { + struct platform_device *pdev; + /* The configuration */ + struct gpiommc_platform_data pdata; ++ /* Mutex to protect this structure */ ++ struct mutex mutex; + }; + + #define GPIO_INVALID -1 +@@ -234,6 +236,8 @@ static ssize_t gpiommc_config_attr_show( + unsigned int gpio; + int err = 0; + ++ mutex_lock(&dev->mutex); ++ + if (attr == &gpiommc_attr_DI) { + gpio = dev->pdata.pins.gpio_di; + if (gpio == GPIO_INVALID) +@@ -294,6 +298,8 @@ static ssize_t gpiommc_config_attr_show( + WARN_ON(1); + err = -ENOSYS; + out: ++ mutex_unlock(&dev->mutex); ++ + return err ? err : count; + } + +@@ -353,6 +359,8 @@ static ssize_t gpiommc_config_attr_store + int err = -EINVAL; + unsigned long data; + ++ mutex_lock(&dev->mutex); ++ + if (attr == &gpiommc_attr_register) { + err = kstrtoul(page, 10, &data); + if (err) +@@ -478,6 +486,8 @@ static ssize_t gpiommc_config_attr_store + WARN_ON(1); + err = -ENOSYS; + out: ++ mutex_unlock(&dev->mutex); ++ + return err ? err : count; + } + +@@ -514,6 +524,7 @@ static struct config_item *gpiommc_make_ + if (!dev) + return NULL; + ++ mutex_init(&dev->mutex); + config_item_init_type_name(&dev->item, name, + &gpiommc_dev_ci_type); + diff --git a/target/linux/generic/patches-4.0/870-hifn795x_byteswap.patch b/target/linux/generic/patches-4.0/870-hifn795x_byteswap.patch new file mode 100644 index 0000000000..3a37c951ec --- /dev/null +++ b/target/linux/generic/patches-4.0/870-hifn795x_byteswap.patch @@ -0,0 +1,17 @@ +--- a/drivers/crypto/hifn_795x.c ++++ b/drivers/crypto/hifn_795x.c +@@ -682,12 +682,12 @@ static inline u32 hifn_read_1(struct hif + + static inline void hifn_write_0(struct hifn_device *dev, u32 reg, u32 val) + { +- writel((__force u32)cpu_to_le32(val), dev->bar[0] + reg); ++ writel(val, dev->bar[0] + reg); + } + + static inline void hifn_write_1(struct hifn_device *dev, u32 reg, u32 val) + { +- writel((__force u32)cpu_to_le32(val), dev->bar[1] + reg); ++ writel(val, dev->bar[1] + reg); + } + + static void hifn_wait_puc(struct hifn_device *dev) diff --git a/target/linux/generic/patches-4.0/880-gateworks_system_controller.patch b/target/linux/generic/patches-4.0/880-gateworks_system_controller.patch new file mode 100644 index 0000000000..32796d5b5a --- /dev/null +++ b/target/linux/generic/patches-4.0/880-gateworks_system_controller.patch @@ -0,0 +1,339 @@ +--- a/drivers/hwmon/Kconfig ++++ b/drivers/hwmon/Kconfig +@@ -507,6 +507,15 @@ config SENSORS_G762 + This driver can also be built as a module.
