From 6b035141f6459df01065f455cbf9c1928f2db16a Mon Sep 17 00:00:00 2001 From: Jeroen Hofstee Date: Sat, 12 Jan 2013 12:07:56 +0000 Subject: [PATCH] common/lcd: cosmetic: clean up a bit - Make the brackets of the function calls more consistent - Remove really unnecessary brackets - Removes the extern from the function definitions - Remove curly brackets from single line statements - Remove lcd_setmem proto since it is already in common.h - Cleanup comments, remove useless comments - Remove NOT_USED_SO_FAR ifdef - Cleanup coding style cc: Anatolij Gustschin Signed-off-by: Jeroen Hofstee [agust: rebased the original patch] Signed-off-by: Anatolij Gustschin --- common/lcd.c | 84 ++++++++++++++++++++------------------------------- include/lcd.h | 38 +++++++++++------------ 2 files changed, 49 insertions(+), 73 deletions(-) diff --git a/common/lcd.c b/common/lcd.c index eceb8ada0d..bd7155fcb9 100644 --- a/common/lcd.c +++ b/common/lcd.c @@ -85,15 +85,13 @@ DECLARE_GLOBAL_DATA_PTR; -ulong lcd_setmem (ulong addr); - static void lcd_drawchars(ushort x, ushort y, uchar *str, int count); static inline void lcd_puts_xy(ushort x, ushort y, uchar *s); static inline void lcd_putc_xy(ushort x, ushort y, uchar c); static int lcd_init(void *lcdbase); -static void *lcd_logo (void); +static void *lcd_logo(void); static int lcd_getbgcolor(void); static void lcd_setfgcolor(int color); @@ -113,13 +111,6 @@ static void *lcd_base; /* Start of framebuffer memory */ static char lcd_flush_dcache; /* 1 to flush dcache after each lcd update */ - -#ifdef NOT_USED_SO_FAR -static void lcd_getcolreg(ushort regno, - ushort *red, ushort *green, ushort *blue); -static int lcd_getfgcolor(void); -#endif /* NOT_USED_SO_FAR */ - /************************************************************************/ /* Flush LCD activity to the caches */ @@ -158,7 +149,7 @@ static void console_scrollup(void) /* Clear the last rows */ memset(lcd_console_address + CONSOLE_SIZE - CONSOLE_ROW_SIZE * rows, COLOR_MASK(lcd_color_bg), - CONSOLE_ROW_SIZE * rows); + CONSOLE_ROW_SIZE * rows); lcd_sync(); console_row -= rows; @@ -170,9 +161,8 @@ static inline void console_back(void) { if (--console_col < 0) { console_col = CONSOLE_COLS-1 ; - if (--console_row < 0) { + if (--console_row < 0) console_row = 0; - } } lcd_putc_xy(console_col * VIDEO_FONT_WIDTH, @@ -183,16 +173,13 @@ static inline void console_back(void) static inline void console_newline(void) { - ++console_row; console_col = 0; /* Check if we need to scroll the terminal */ - if (console_row >= CONSOLE_ROWS) { - /* Scroll everything up */ + if (++console_row >= CONSOLE_ROWS) console_scrollup(); - } else { + else lcd_sync(); - } } /*----------------------------------------------------------------------*/ @@ -244,9 +231,9 @@ void lcd_puts(const char *s) return; } - while (*s) { + while (*s) lcd_putc(*s++); - } + lcd_sync(); } @@ -293,7 +280,7 @@ static void lcd_drawchars(ushort x, ushort y, uchar *str, int count) #endif #if LCD_BPP == LCD_MONOCHROME - uchar rest = *d & -(1 << (8-off)); + uchar rest = *d & -(1 << (8 - off)); uchar sym; #endif for (i = 0; i < count; ++i) { @@ -323,7 +310,7 @@ static void lcd_drawchars(ushort x, ushort y, uchar *str, int count) #endif } #if LCD_BPP == LCD_MONOCHROME - *d = rest | (*d & ((1 << (8-off)) - 1)); + *d = rest | (*d & ((1 << (8 - off)) - 1)); #endif } } @@ -350,7 +337,7 @@ static inline void lcd_putc_xy(ushort x, ushort y, uchar c) #define N_BLK_VERT 2 #define N_BLK_HOR 3 -static int test_colors[N_BLK_HOR*N_BLK_VERT] = { +static int test_colors[N_BLK_HOR * N_BLK_VERT] = { CONSOLE_COLOR_RED, CONSOLE_COLOR_GREEN, CONSOLE_COLOR_YELLOW, CONSOLE_COLOR_BLUE, CONSOLE_COLOR_MAGENTA, CONSOLE_COLOR_CYAN, }; @@ -371,7 +358,7 @@ static void test_pattern(void) for (v = 0; v < v_max; ++v) { uchar iy = v / v_step; for (h = 0; h < h_max; ++h) { - uchar ix = N_BLK_HOR * iy + (h/h_step); + uchar ix = N_BLK_HOR * iy + h / h_step; *pix++ = test_colors[ix]; } } @@ -389,12 +376,12 @@ int lcd_get_size(int *line_length) return *line_length * panel_info.vl_row; } -int drv_lcd_init (void) +int drv_lcd_init(void) { struct stdio_dev lcddev; int rc; - lcd_base = (void *)(gd->fb_base); + lcd_base = (void *) gd->fb_base; lcd_get_size(&lcd_line_length); @@ -409,7 +396,7 @@ int drv_lcd_init (void) lcddev.putc = lcd_putc; /* 'putc' function */ lcddev.puts = lcd_puts; /* 'puts' function */ - rc = stdio_register (&lcddev); + rc = stdio_register(&lcddev); return (rc == 0) ?
