Pcie controller and pcie phy -drivers for this soc which are still in staging git tree make uses -of 'soc_device_attribute' looking for revision 'E2' in order to -know if reset lines are or not inverted. This way of doing things -seems to be necessary in order to make things clean and properly. -Hence, introduce this 'soc_device' to be able to properly use those -attributes in drivers. Also set 'data' pointer points to the struct -'ralink_soc_info' to be able to export also current soc information -using this mechanism. - -Cc: Paul Burton <paul.burton@mips.com> -Cc: ralf@linux-mips.org -Cc: jhogan@kernel.org -Cc: john@phrozen.org -Cc: NeilBrown <neil@brown.name> -Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> -Cc: linux-mips@vger.kernel.org - -Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> -Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> ---- - arch/mips/ralink/mt7621.c | 32 +++++++++++++++++++++++++++++++- - 1 file changed, 31 insertions(+), 1 deletion(-) - ---- a/arch/mips/ralink/mt7621.c -+++ b/arch/mips/ralink/mt7621.c -@@ -7,6 +7,8 @@ - - #include <linux/kernel.h> - #include <linux/init.h> -+#include <linux/slab.h> -+#include <linux/sys_soc.h> - #include <linux/jiffies.h> - #include <linux/clk.h> - #include <linux/clkdev.h> -@@ -294,6 +296,33 @@ static int udelay_recal(void) - } - device_initcall(udelay_recal); - -+static void soc_dev_init(struct ralink_soc_info *soc_info, u32 rev) -+{ -+ struct soc_device *soc_dev; -+ struct soc_device_attribute *soc_dev_attr; -+ -+ soc_dev_attr = kzalloc(sizeof(*soc_dev_attr), GFP_KERNEL); -+ if (!soc_dev_attr) -+ return; -+ -+ soc_dev_attr->soc_id = "mt7621"; -+ soc_dev_attr->family = "Ralink"; -+ -+ if (((rev >> CHIP_REV_VER_SHIFT) & CHIP_REV_VER_MASK) == 1 && -+ (rev & CHIP_REV_ECO_MASK) == 1) -+ soc_dev_attr->revision = "E2"; -+ else -+ soc_dev_attr->revision = "E1"; -+ -+ soc_dev_attr->data = soc_info; -+ -+ soc_dev = soc_device_register(soc_dev_attr); -+ if (IS_ERR(soc_dev)) { -+ kfree(soc_dev_attr); -+ return; -+ } -+} -+ - void prom_soc_init(struct ralink_soc_info *soc_info) - { - void __iomem *sysc = (void __iomem *) KSEG1ADDR(MT7621_SYSC_BASE); -@@ -345,11 +374,12 @@ void prom_soc_init(struct ralink_soc_inf - soc_info->mem_detect = mt7621_memory_detect; - rt2880_pinmux_data = mt7621_pinmux_data; - -- - if (!register_cps_smp_ops()) - return; - if (!register_cmp_smp_ops()) - return; - if (!register_vsmp_smp_ops()) - return; -+ -+ soc_dev_init(soc_info, rev); - } |
