| * Abolish cpu_read* and cpu_write* accessorsMasahiro Yamada2015-05-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2e6a88f2101d (add cpu native ordered io accessors) introduced these macros and then commit be57f20cdd7d (Fix big endian MMIO primitives) figured out they are equivalent to __raw_{read,write}*. They turned out unnecessary after all. Anyway, most source files use __raw_read* and __raw_write*. Let's replace a few remaining references and abolish them.

* of: use 'const void *' for struct of_device_id.dataAntony Pavlov2015-04-303-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 2011 barebox' of_device_id struct uses unsigned long type for data field: struct of_device_id { char *compatible; unsigned long data; }; Almost always struct of_device_id.data field are used as pointer and need 'unsigned long' casting. E.g. see 'git grep -A 4 of_device_id drivers/' output: drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = { drivers/ata/sata-imx.c- { drivers/ata/sata-imx.c- .compatible = "fsl,imx6q-ahci", drivers/ata/sata-imx.c- .data = (unsigned long)&data_imx6, drivers/ata/sata-imx.c- }, { Here is of_device_id struct in linux kernel v4.0: struct of_device_id { char name[32]; char type[32]; char compatible[128]; const void *data; }; Changing of_device_id.data type to 'const void *data' will increase barebox' linux kernel compatibility and decrease number of 'unsigned long' casts. Part of the patch was done using the 'coccinelle' tool with the following semantic patch: @rule1@ identifier dev; identifier type; identifier func; @@ func(...) { <... - dev_get_drvdata(dev, (unsigned long *)&type) + dev_get_drvdata(dev, (const void **)&type) ...> } @rule2@ identifier dev; identifier type; identifier func; identifier data; @@ func(...) { <... - dev_get_drvdata(dev, (unsigned long *)&type->data) + dev_get_drvdata(dev, (const void **)&type->data) ...> } Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* serial: imx: Fix buggy transmissions when baudrate mismatchesFabio Estevam2014-06-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bit 7 of UCR3 is described in the i.MX reference manuals (with the exception of i.MX1) as follows: ADNIMP: Autobaud Detection Not Improved-. Disables new features of autobaud detection (See Baud Rate Automatic Detection Protocol, for more details). 0 Autobaud detection new features selected 1 Keep old autobaud detection mechanism The "new features" mechanism occasionally causes the receiver to get out of sync and continuously produces received characters of '0xff'. In order to reproduce the problem: $ cs0.baudrate=19200 - Change the terminal baudrate to 19200 - Type in the console and it should look good - Change the terminal baudrate back to 115200 - Type 'b' in the console, then a stream of '0xff' is transmitted in loop Setting the ADNIMP bit avoids the transmission of '0xff' in loop. Also rename the bit definition as per the reference manual. Tested on mx6q. Based on a patch from Eric Nelson for U-boot.

| | | | | | | | | | | | | | | | | | | | | | | | The current implementation fakes a memory-mapped I/O device at 0x3f8 and 0x2f8, then uses platform read/write functions to do the actual reading and writing. These platform functions only exist for the x86 platform; better to move the I/O routines into the driver and have the driver request I/O ports using request_ioport_region.
