* ARM: mxs: Move mach header files to include/mach/mxsSascha Hauer2023-03-061-5/+5
| | | | | | | | | | Currently arch specific headers can be included with longer possible as there won't be a single mach anymore. Move all mxs specific header files to include/mach/mxs/ to prepare for multi-arch support. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* treewide: Make locally used functions staticSascha Hauer2019-03-181-5/+5
| | | | | | | Many functions are only used locally but still are globally visible. Make these function static. Avoids warnings generated with -Wmissing-prototypes Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: MXS: allow configuration of EMI clock prescalerRoland Hieber2018-08-141-10/+9
| | | | | | | | | | | | | Allow to set not only the fractional divider, but also the prescaler for the EMI clock in mxs_mem_init_clock(), and rename the parameters accordingly to reflect the change. Port the existing board code to set up the EMI clock explicitely with the old values. Also fix the off-by-a-half error in the comments, which did not take the prescaler of 2 into account, on which the fractional divider is applied (according to the i.MX23/i.MX28 Reference Manuals) Signed-off-by: Roland Hieber <r.hieber@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: MXS: i.MX28: allow setup of low-voltage SDRAMRoland Hieber2018-08-141-6/+3
| | | | | | | | The PINCTRL_*_DDR_MODE_* defines are now needed in global scope, so move them to the respective include header. Signed-off-by: Roland Hieber <r.hieber@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: mxs: add parameter to mx28_mem_init to allow custom memory configUwe Kleine-König2016-05-101-6/+6
| | | | | | | | | | Rename the already global array of default memory settings to make the intended usage more obvious. Also make generous use of the const keyword. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: mxs: Add lowlevel setup from U-BootSascha Hauer2015-01-051-0/+371
U-Boot has code to replace the infamous Freescale bootlet code. This patch adds this for barebox with some changes: - Separate it more into mx23/mx28 functions instead of mxs functions with #ifdefs for the actual SoC - Add mx2x_power_init_battery_input() power entry point for boards which have a regulated input on the battery pin to supply the board. - Export more functions to be more flexible when boards need non standard setup.
